The best ATV rear seat storage choice depends on whether you need a hard, weather-resistant cargo box, a passenger-style padded seat, or flexible bag storage. The VEVOR model offers a stated 95-liter capacity with a seat and backrest; the Black Boar and Guide Gear options combine seating with storage; and the KEMIMOTO bag suits riders who prefer a soft, adjustable carrier. Compare capacity, mounting information, and fit before choosing.

Black Boar ATV Rear Storage Box & Lounger Seat

This Black Boar model combines a cushioned rear lounger with two separate cargo bins, providing about 2 cubic feet of total storage. Its lower bin offers 1.5 cubic feet of lockable, sealed storage, while the upper half-cubic-foot bin can be accessed while seated.
Best for: ATV owners who want a passenger-style seat and divided storage in one unit. The product is listed as compatible with most tubular racks, and mounting hardware is included inside the storage box.
Consideration: The stated compatibility is for most tubular racks, not every rack style. Check your rack before buying. The upper bin is smaller than the lower compartment.
ATV Trunk & Lounger

This ATV trunk and lounger has a stated capacity of 31 gallons, or 117 liters, making it the largest listed capacity among these five products. Its roto-molded construction is described as durable, and the hinge-and-gutter design is intended to keep the interior dry and free of dust.
Best for: Riders who prioritize a large enclosed cargo area and want a lounger-style product. The capacity is useful for comparing it with smaller seat boxes and the 55-liter soft bag.
Consideration: The supplied product details do not specify rack compatibility, mounting hardware, or lock features. Confirm those requirements before choosing it for a particular ATV.
Guide Gear ATV Lounger Seat With Storage

The Guide Gear lounger pairs a large cushion and padded backrest with a rear storage compartment described as spacious enough for two helmets. It mounts to most ATV tubular racks using four U-bolts and sealing washers, with fixtures included.
Best for: Riders who want a cushioned rear seat and dedicated helmet storage. Its stated four-U-bolt mounting setup gives buyers a specific rack style and installation detail to check against their ATV.
Consideration: The listed details do not provide a capacity measurement or state that the compartment is lockable. Choose another option if those are essential requirements.
KEMIMOTO 55L ATV Rear Seat Storage Bag

This soft-sided rear bag has 55 liters of stated capacity and measures 33.07 by 17.3 by 9.05 inches. Adjustable elastic and self-fastening straps accommodate different cargo, while three removable internal shelves help organize gear. Two outside pockets are sized for items such as drinks under 3.5 inches in diameter.
Best for: Riders who want adjustable, organized cargo storage rather than a hard box with an integrated seat. The bag has an internal frame, grab handles, and covered YKK zippers.
Consideration: Measure the ATV seat or rack area before ordering; the listed bag length is 33.07 inches. The top is specified to carry a maximum of 5 kilograms.
VEVOR 95L ATV Rear Storage Box and Lounger

The VEVOR combines a rear seat and backrest with a 95-liter cargo compartment. Its listed dimensions are 42.5 by 24.8 by 16.9 inches. The box is made from LLDPE using a rotomolding process and is described as waterproof, dustproof, and resistant to abrasion and scratches. A padded seat and back pad add cushioning.
Best for: Buyers seeking a large hard box with integrated seating and a stated lockable design. It is listed to fit most ATVs with a rear rack and is described as compatible with ATV, UTV, and Can-Am vehicles.
Consideration: Its dimensions make rack fit an important check. Confirm the available rack space and vehicle fit before purchase.
Buying Guide: How To Choose An ATV Rear Seat Storage Box
Do you need a hard box or a soft bag?
A hard box is the better match when you want enclosed storage and an integrated lounger. The VEVOR lists waterproof construction, while the 31-gallon ATV Trunk & Lounger describes a hinge-and-gutter design intended to keep out moisture and dust. The KEMIMOTO is a soft bag with adjustable straps and removable shelves, which can suit riders who value flexible organization.
How much storage capacity is enough?
Compare stated volumes where available: the Black Boar offers about 2 cubic feet, the KEMIMOTO 55 liters, the VEVOR 95 liters, and the ATV Trunk & Lounger 31 gallons. These measurements use different units, so convert them if you need a direct volume comparison. Check the product dimensions as well, especially if your cargo includes helmets or long items.
Will the box fit your ATV rack?
Check rack type, available surface area, and mounting hardware. Black Boar and Guide Gear specify compatibility with most tubular racks, while the VEVOR is listed for most ATVs with a rear rack. The supplied details for the 31-gallon trunk do not specify mounting requirements. Do not assume that a universal-style claim guarantees fit on every vehicle.
Is the rear seat intended for passengers?
Several products are described as loungers or include a seat and backrest, but the supplied features do not establish passenger capacity or vehicle-specific passenger approval. Review the product instructions and your ATV manufacturer’s guidance before carrying another rider.
