The Keter Marvel Plus 71-Gallon Deck Box suits patios that need cushion storage and an extra seat in a relatively shallow footprint. Its 71-gallon capacity is smaller than the Kentwood and Devoko options, so check the dimensions against your gear before choosing it.
It makes the most sense for cushions, pool accessories, beach towels or garden tools that fit its 44.6 x 15.6 x 20 in interior. For a larger load, the Kentwood or Devoko offers more capacity.
The Keter Marvel Plus review at a glance
The Marvel Plus combines 71 gallons of resin storage with a seat rated up to 485 lb. Its 17.4 in exterior depth is a useful detail if a deeper box would crowd a walkway.
Keter Marvel Plus 71 Gal Deck Box: Best for compact cushion storage
- 71-gallon capacity
- 45.9 x 17.4 x 22.2 in exterior
- 485 lb seat capacity
- Tool-free assembly
A relatively shallow deck box for patio cushions, pool accessories and garden tools, with bench seating built into the lid.
Pros
- Shallow 17.4 in exterior depth
- Wood-look resin texture
- Supports up to 485 lb as a seat
- Assembly requires no extra tools
Cons
- Less capacity than the larger options here
- Interior depth is 15.6 in
The wood-look texture gives the resin a more traditional patio appearance. The box is made from weather-resistant polypropylene, and Keter says its construction resists rusting, peeling and denting.
Who should choose the Marvel Plus?
Choose it if you want to store patio cushions, pool supplies or small garden tools close to where you'll use them. The interior dimensions matter more than the gallon figure when you're checking whether bulky cushions or long tools will fit.
Skip it if you need to store a large set of thick cushions or several bulky items together. The Kentwood offers 92 gallons and the Devoko offers 100 gallons, though both need more depth.
What fits inside the 71-gallon box?
The Marvel Plus fits smaller outdoor items that work with its 15.6 in interior depth. Cushions, throw pillows, beach towels and pool accessories are among the uses Keter names.
Measure the largest item, including cushion thickness when compressed only by normal placement. Don't plan on forcing a lid closed over an overfilled box, since that can make everyday access awkward.
The interior is 44.6 in wide and 20 in high. For garden tools, compare their length and handle shape with those measurements before buying.

How does it compare with the other deck boxes?
The Marvel Plus is the shallowest option here by exterior depth, while the Devoko has the most capacity. The right fit depends on whether you value compact placement or extra room.
| Product | Capacity | Exterior dimensions | Seat capacity |
|---|---|---|---|
| Keter Marvel Plus | 71 gallons | 45.9 x 17.4 x 22.2 in | 485 lb |
| Keter Kentwood | 92 gallons | 50.4 x 21.2 x 23.2 in | 441 lb |
| Devoko | 100 gallons | 48 x 22 x 24.5 in | 500 lb |
| EAST OAK | 60 gallons | 42.1 x 17 x 21.6 in | 660 lb |
The Kentwood adds 21 gallons over the Marvel Plus, with a lockable lid. The Devoko has 29 more gallons than the Marvel Plus and gas rods for easier opening and slow closing.
The EAST OAK trades capacity for a smaller box and a higher stated seat limit. Our Keter and Lifetime deck box comparison looks at another brand choice if you're still weighing Keter against a different maker.
Is the Marvel Plus easy to place and assemble?
The Marvel Plus is 45.9 in wide, 17.4 in deep and 22.2 in high, so it takes less depth than the other boxes in this comparison. Leave room to open the lid and reach inside, not just enough for the footprint.
Keter describes assembly as simple, quick and requiring no extra tools. Lay out the parts on a level surface and follow the instructions in order, especially before using the box as a seat.
The listed weight is 16 ounces, which seems unusual for a deck box. Don't use that figure to plan handling; check the current product details or ask the seller if shipping or lifting weight matters to you.
Will the contents stay dry outdoors?
The Marvel Plus is described as weather resistant, but that doesn't mean every stored item will stay dry in all conditions. Check the fit and lid closure after assembly, and avoid storing valuables or fabrics that must remain completely dry.
Place it on a firm, level surface so the lid can close as intended. In a covered patio, it can also keep cushions and towels near the seating area without exposing them to direct weather.
For general protection, read our guide on keeping a shed dry through every season. The same habits of checking drainage and keeping stored goods off wet ground can help patio storage last longer.
Is the Keter Marvel Plus worth choosing?
The Marvel Plus is a good match for compact cushion storage and occasional seating when its interior dimensions work for your items. It gives up capacity to the larger Kentwood and Devoko, but takes less depth.
Choose the Marvel Plus if your patio has limited depth and 71 gallons covers your storage needs. Pick the Kentwood for a larger Keter box with a lockable lid, the Devoko when capacity matters most, or EAST OAK for a smaller box with a higher stated seat capacity.

How much can the Keter Marvel Plus hold?

Can you sit on the Keter Marvel Plus?
Yes. Keter gives the Marvel Plus a bench seat capacity of up to 485 lb.
