Adding a second seat to your ATV changes the entire dynamic of a ride. Whether you are hauling a passenger across a rocky trail or giving a younger rider a secure spot behind you, the seat itself determines safety, comfort, and how much gear you can still carry. Not every mount, frame, or cushion layout fits the same machine or rider weight range.

Any trail rider valuing passenger comfort and cargo versatility will find the best atv two up seat transforms their machine into a true companion.
How To Choose The Best ATV Two Up Seat
Selecting a two-up seat for an ATV involves more than grabbing the widest cushion available. Mounting type, frame construction, passenger weight limits, and storage integration all determine whether the seat becomes a trusted daily accessory or a nuisance on the trail. Understanding these factors keeps you from wasting time on a seat that shifts, cracks, or simply doesn’t fit your rack layout.
Mounting Orientation and Frame Fit
Jump seats typically mount rear-facing on the cargo rack, while lounger-style seats sit forward-facing and often double as storage trunks. Check whether your ATV rack uses tubular bars or a stamped steel platform. Universal seats with adjustable brackets fit a wider range of machines but may require drilling or shimming for a rock-solid install. Vehicle-specific models, such as those made for the Kawasaki Teryx 4, eliminate guesswork but narrow your replacement options later.
Passenger Weight Limits and Safety Restraints
Every two-up seat has a stated load capacity, and exceeding it compromises both the frame welds and the passenger’s safety. Junior seats designed for riders under 70 pounds often include harness slots or integrated 4-point belts. Full-size seats should accommodate at least 200 pounds and include a secure restraint system. A seat that flips up for cargo access offers convenience but demands robust hinge hardware to avoid fatigue failures over rough terrain.
Material Construction and Weather Resistance
Marine-grade vinyl, roto-molded polyethylene, and powder-coated steel represent the three tiers of durability. Vinyl resists UV and cleans easily but can tear if punctured. Roto-molded trunks offer structural rigidity and weather seals but add weight. Powder-coated steel frames prevent corrosion beneath the cushion. Seats sold as “water-resistant” often lack the full gutter seals of higher-end trunks, so consider your typical riding conditions before deciding on a budget-friendly option.

In‑Depth Reviews
1. Black Boar ATV Rear Storage Box & Lounger
The Black Boar Rear Lounger bridges the gap between a comfortable passenger perch and a serious cargo trunk better than any universal option I have seen in the spec sheets. Its dual-bin design gives you about two cubic feet of total storage, with the lower bin featuring a stainless steel lock for security. The seat cushion measures 12 by 20 inches, and the lumbar support pad adds another 15 inches of back comfort, making it suitable for longer trail rides.
Mounting hardware is included inside the box, and the unit attaches to most tubular racks without requiring custom brackets. The polymer construction keeps weight at 33.7 pounds, which is reasonable for a trunk this size. Two built-in cupholders are a thoughtful touch that many competitive products omit entirely. Black Boar explicitly notes the lounger should be used when the vehicle is stationary, so this is a camp-base or break-time seat rather than a moving jump seat.
Owner reports consistently praise the locking mechanism and the ease of accessing the lower bin without unloading the upper tray. The trade-off is that this unit is not designed for in-motion passenger use, so riders who need a true moving jump seat should look elsewhere. For riders who want a secure storage upgrade with a comfortable stationary seat, this represents the strongest blend of features in the category.
What works
- Lockable stainless steel latch adds real theft deterrence
- Two cupholders integrated into the lid
- Lumbar and upper back pads improve stationary comfort
What doesn’t
- Not rated for occupant use while vehicle is moving
- Universal mount may require drilling on non-tubular racks
- Polymer shell can crack under extreme cold if over-tightened
2. Can-Am OEM Passenger Seat Assembly for Ryker
This genuine Can-Am assembly is the definitive solution for converting a Ryker from a single-rider machine into a two-up configuration. The kit includes the passenger seat, handles, and retractable foot pegs, so nothing is left to third-party guesswork. The peg mechanism communicates with the vehicle’s VSS calibration system when flipped out, ensuring the speedometer and stability controls account for the additional rider weight.
Installation requires the MAX Mount base, sold separately, but the process is straightforward for anyone comfortable removing the rear body panel. The seat material matches the stock front saddle exactly, so the visual uniformity is preserved. At just three pounds total, the assembly adds negligible weight while expanding the Ryker’s capability considerably.
Buyer feedback highlights how seamlessly the pegs retract when not in use and how the handles provide a natural grip for the passenger. The limitation is obvious: this only fits Can-Am Ryker models with the MAX Mount interface. Owners of other ATV or UTV brands will need to look at universal alternatives. For Ryker owners, however, this is the only OEM-grade path to a two-up setup.
What works
- Complete OEM kit with seat, handles, and pegs
- Pegs integrate with VSS passenger calibration
- Matches stock seat material and appearance
What doesn’t
- Requires MAX Mount base not included in the box
- Exclusive to Can-Am Ryker models only
- Limited to a single passenger orientation
3. UTVMA Rear Bump Seat for Kawasaki Teryx 4
UTVMA designed this center bump seat exclusively for the Kawasaki Teryx 4 model years 2012 through 2025, making it a drop-in safety upgrade for owners who want to carry an extra passenger between the rear factory seats. The seat comes with a 4-point harness that includes sewn-in pads and a chest buckle, which is significantly more secure than a standard lap belt. The vinyl exterior resists water, mud, and UV exposure, which aligns with the abuse a trail rig sees.
At eleven pounds, the unit is light enough to install and remove without straining, and the mounting bracket is included. The padding thickness is generous enough that passenger reports describe a stable ride even over choppy terrain. UTVMA explicitly states this is for off-road use only, so it should never be used on public highways or at high speed.
Owner feedback consistently confirms the fitment precision on Teryx 4 models, though several note that it does not work with KRX platforms at all. The harness adjusters allow for a snug fit across different rider sizes, and the chest buckle prevents the shoulder straps from sliding off smaller passengers. The main drawback is the lack of headrest support, which taller riders may find uncomfortable over long distances.
What works
- Precision fit for Teryx 4 models 2012-2025
- 4-point harness with padded chest buckle included
- Weather-resistant vinyl stands up to mud and rain
What doesn’t
- Incompatible with Kawasaki KRX models
- No headrest support for taller passengers
- Off-road use only with no highway rating
4. Kimpex NOMAD Trunk
The Kimpex NOMAD Trunk sits at the top of the storage-first category with a massive 115-liter volume that can hold two MX helmets plus gear. The steel frame adds structural rigidity that prevents the box from flexing under heavy loads, and the insert-mount system secures the trunk to the ATV rack without excessive hardware. The closure type is lockable, which is a basic requirement for anyone leaving gear unattended on the trail.
Dimensions of 43 by 30 by 17 inches mean this trunk occupies most of the rear rack, so it is best suited for riders who prioritize cargo capacity over having a separate passenger seat. The 34-pound weight is noticeable during installation but becomes irrelevant once mounted. Kimpex does not include a brake light or heated grips, keeping the feature set focused purely on storage volume.
Reports from owners indicate the steel frame holds up well on rough trails and the lid seals keep dust out during dry rides. The lack of a gutter seal for wet conditions means this trunk is water-resistant rather than waterproof, so sensitive items should be packed in dry bags inside. Riders who need both a passenger seat and storage may find the NOMAD too bulky for dual use.
What works
- 115-liter capacity fits two helmets with room to spare
- Steel frame eliminates flex under heavy loads
- Lockable lid adds basic security
What doesn’t
- Not fully waterproof; dust seals only
- No brake light or heated grip integration
- Heavy at 34 pounds before loading
5. Kimpex Outback 2.0 Trunk Rear
The Kimpex Outback 2.0 Trunk offers a slightly lower profile than the NOMAD while still accommodating two helmets inside its 42-by-28-by-17-inch interior volume. It mounts in the rear position and weighs 31 pounds, making it one of the lighter premium trunk options available. The design emphasizes a clean exterior with no protruding hinges or latches that could snag on brush.
Helmet capacity is listed as two, though the actual fit depends on helmet size and shape. The trunk lacks a key lock, so security relies solely on the latch mechanism. Kimpex does not include heated grips or a brake light, keeping the unit purely focused on storage and occasional seating when stationary.
Owners report that the trunk maintains a dry interior in light rain but should not be trusted in a downpour without additional sealing. The mounting hardware is straightforward, and the trunk sits low enough to avoid blocking rear visibility on most ATVs. The absence of a locking mechanism is the most common point of criticism, especially for riders who park overnight on multi-day trips.
What works
- Compact profile fits well on smaller ATV racks
- Lightweight at 31 pounds for its volume
- Two-helmet capacity with no overhang
What doesn’t
- No lock included for security
- Not fully waterproof in heavy rain
- Lacks heated grip or brake light options
6. TCMT 96L ATV Rear Passenger Seat Rack Cargo Storage
TCMT’s 96-liter cargo trunk offers a universal fit for most ATVs at a mid-range price point that undercuts many premium competitors while still delivering robust LLDPE construction. Linear low-density polyethylene is impact-resistant and won’t crack as easily as cheaper ABS plastic under trail vibration. The 22.7-pound weight makes it one of the lighter large-capacity trunks on the market, reducing the load on the rear rack.
The trunk mounts as a rear rack accessory and can double as a stationary seat, though TCMT markets it primarily as a cargo solution. The 96-liter volume is sufficient for a weekend’s worth of gear or two smaller helmets. The exterior finish is a smooth black texture that hides scratches reasonably well.
Buyer feedback mentions the hardware holds up well during installation, though the included bolts may not match every ATV rack hole pattern. Some owners have added weatherstripping to improve the dust seal. The lack of a lockable latch is the most frequent disappointment, but the overall build quality at this price tier earns consistent praise for value-minded shoppers.
What works
- LLDPE construction resists impact and cracking
- Lightweight at 22.7 pounds for the capacity
- Universal fit works with most ATV racks
What doesn’t
- No integrated lock for security
- Seal allows dust ingress without modification
- Bolts may require drilling on non-standard racks
7. UTV Junior Seat 5 Point Harness
This Aces Racing UTV Junior Seat comes equipped with a 5-point harness, making it one of the safest options for carrying a child passenger inside a full-size UTV or ATV seat. The padded bottom rests directly on the existing seat surface to prevent damage to the upholstery underneath. The harness webbing is 2-inch wide material compatible with most aftermarket mount points.
The seat fits inside both stock and aftermarket seats, meaning you do not need to replace the factory buckets to accommodate a younger rider. Aces Racing rates it for off-road use only, which is standard for this type of add-on seat. The fabric and foam construction keeps weight low, and the harness adjusters allow for a custom fit as the child grows.
Owner installers note that the seat stays in place well during moderate trail riding, though aggressive cornering can shift it if the harness is not tightly anchored. The 70-pound weight limit is clearly stated, and exceeding it puts both the child and the harness integrity at risk. For families bringing a younger rider along without buying a second machine, this is a focused safety upgrade.
What works
- 5-point harness provides superior child restraint
- Padded bottom protects existing seat upholstery
- Fits both stock and aftermarket seats
What doesn’t
- 70-pound weight limit restricts rider size
- Can shift under aggressive cornering if not anchored
- Off-road only, no highway safety certification
8. Aces Racing Junior Seat
The Aces Racing Junior Seat provides a budget-friendly entry point for adding a child seat inside a UTV or ATV without modifying the existing seat structure. It is built from marine-grade carbon vinyl that resists UV fading and cleans easily after muddy rides. The seat fits both stock and aftermarket seats across Polaris, Can-Am, Yamaha, Honda, and other major brands.
This version is designed for a 4 or 5-point harness with 2-inch webbing, but the harness itself is not included, which keeps the initial cost lower for buyers who already own a compatible restraint system. The seat depth measures 15 inches, the width is 10 inches, and the total height reaches 27 inches, making it compact enough to fit without crowding the front rider. Aces Racing specifies a 70-pound maximum passenger weight.
Feedback from buyers highlights the ease of installation and the secure fit once the harness is threaded through the shoulder and hip slots. The vinyl material holds up well against mud splatter and sun exposure. The absence of an included harness is the most common complaint, as some buyers do not realize they need to supply the restraint separately.
What works
- Marine-grade vinyl withstands UV and mud
- Compact dimensions fit most UTV/ATV seats
- Works with 4 or 5-point harness systems
What doesn’t
- Harness not included with the seat
- 70-pound weight limit limits rider size
- Vinyl can tear if snagged on sharp cargo
9. Kolpin ATV Trunk & Lounger
Kolpin’s ATV Trunk & Lounger uses roto-molded construction to deliver a 31-gallon storage capacity with a seamless hinge and gutter design that keeps the interior dry and dust-free. This is a significant advantage over trunks that rely on basic overlid seals. The unit is made in the USA from global materials, which appeals to buyers who prioritize domestic manufacturing.
The trunk doubles as a stationary lounger with removable no-slip seat pads, allowing two riders to sit comfortably when the ATV is parked. Heavy-duty rubber draw latches hold the lid securely, and integrated padlock holes add an extra layer of security. Rugged mounting tie-downs provide flexibility for attaching the trunk to various rack configurations.
Owner reports emphasize the waterproof performance of the gutter seal, with many describing gear staying completely dry after creek crossings and heavy rain. The roto-molded plastic is thick enough to resist cracking from trail impacts. The 2-pound listed weight appears to be an error in the product data, as the construction clearly requires more mass, and users confirm the unit feels substantial when mounted.
What works
- Seamless gutter design keeps interior dry
- Roto-molded construction resists cracking
- Tie-downs allow flexible mounting options
What doesn’t
- Stationary lounger only, not for moving rides
- Large footprint may overhang smaller racks
- Weight feels heavier than listed spec suggests
10. YUTRAX Universal Mount UTV Jump Seat
The YUTRAX Universal Jump Seat offers a no-frills way to add a rear-facing passenger seat to most UTVs at an entry-level price. The heavy-duty powder-coated steel frame supports a water-resistant padded seat and backrest, and the entire unit flips up to grant full access to the cargo box when the passenger is not riding. Seat belts are included in the package, so there are no hidden costs after purchase.
Installation is straightforward with the included hardware, and the universal design aims to fit a wide range of UTV rack layouts. The seat’s rear-facing orientation means the passenger faces backward during travel, which is standard for jump seats but may take some getting used to. YUTRAX backs the seat with a 1-year limited warranty, adding a layer of buyer protection uncommon at this price level.
User feedback notes that the seat feels stable on groomed trails and moderate terrain, though the padding is firmer than premium options. The flip-up mechanism works reliably when the seat is not loaded. Some owners have reinforced the hinge brackets with additional fasteners for peace of mind on rougher routes. For budget-conscious buyers who need a functional second seat without frills, this delivers the essentials.
What works
- Flip-up design preserves full cargo box access
- Seat belts included at no extra cost
- 1-year warranty backs the purchase
What doesn’t
- Firm padding limits comfort on long rides
- Rear-facing orientation not preferred by all passengers
- Hinge brackets may need reinforcement for rough terrain
11. Coleman Powersports B200 Minibike
The Coleman Powersports B200 occupies a different category entirely — it is a standalone 196cc gas-powered minibike rather than a seat accessory. For ATV owners whose passenger wants their own machine instead of riding two-up, this provides an independent ride that follows along on the trail. The 4-stroke OHV engine delivers up to 30 mph, and the heavy-duty frame supports a 200-pound maximum load.
The minibike features low-pressure tires paired with double shock absorbers to smooth out trail chatter. A bright headlight extends riding time into low-light conditions, and the recoil pull-start system requires no battery maintenance. Coleman rates the B200 for both kids and adults, with the caveat that riders must be capable of reaching the controls and handling the 154-pound machine.
Buyer reviews consistently praise the engine reliability and the ease of starting, even after long storage periods. The minibike is not a direct substitute for a two-up seat, but it solves the same underlying need: bringing a second person along on the adventure. Families with older children or lighter adults often pair this with their ATV to give everyone their own set of handlebars.
What works
- Reliable 196cc OHV engine with easy pull-start
- Dual shock absorbers smooth out rough trails
- Headlight allows riding in low-light conditions
What doesn’t
- Not a seat accessory — requires separate rider license
- 154-pound weight makes it heavy to load in a truck bed
- 200-pound limit restricts larger riders
Hardware & Specs Guide
Frame Materials
Powder-coated steel frames offer the best strength-to-weight ratio for jump seats that support passenger loads on bumpy terrain. Alloy steel frames add corrosion resistance but increase cost. Roto-molded polyethylene trunks use a single-piece construction that eliminates weld points but relies on material thickness for strength. LLDPE provides impact resistance without the brittleness of ABS plastic.
Weight and Capacity Limits
Manufacturers specify both the seat weight and the maximum passenger load. Junior seats top out around 70 pounds, while full-size jump seats typically handle 200 pounds or more. Trunk-style loungers cap occupant weight lower since they are designed for stationary use. Exceeding these limits risks frame deformation, hinge failure, or harness detachment during a ride.
Mounting Systems
Universal jump seats use adjustable brackets and U-bolts that wrap around tubular racks. Vehicle-specific models use pre-drilled holes and matching hardware for a bolt-on fit. Flip-up seats rely on heavy-duty hinges and latch pins that must endure repeated cycling. Trunk mounts typically use threaded inserts or steel tie-down plates that sandwich the rack rails.
Harness and Safety Features
Integrated seat belts are common on dedicated jump seats, while junior seats rely on 4-point or 5-point harnesses threaded through fabric slots. The webbing width is standard 2 inches for most UTV harness systems. Some OEM seats include retractable pegs that trigger passenger calibration in the vehicle’s computer. Stationary loungers omit harnesses entirely and rely on the passenger staying seated while parked.
