A deck box keeps cushions, pool gear, and garden tools dry, and it doubles as extra seating. This comparison covers one extra large deck box each from Keter, Suncast, and Lifetime, all in the 130 to 150 gallon range, which is the size most patios need for a full set of chair cushions.
How We Chose
We picked the three best known deck box brands that sell a 130 to 150 gallon box on Amazon and compared price, capacity, size, and features. We added a cost per gallon column to make the price gap easy to see. This is a researched comparison, not a hands-on test of these boxes, so the comparison rests on manufacturer specifications and Amazon listing details. All three listings are available on Amazon. Prices are Amazon prices checked in September 2026 and can change, and prices vary by color. The boxes we priced are the Keter Westwood in Taupe (item 263752), the Suncast BMDB1340DG in Dove Gray, and the Lifetime 60012. Lifetime’s page does not publish dimensions, so that cell uses the Amazon listing. Every spec and warranty cell in the table comes from each manufacturer’s own website and names the page, checked in September 2026. Where a manufacturer page covers a product line and does not name the model, or gives no length, the cell says so, and terms can differ by size or color, so confirm before you buy.

Lifetime’s box is made of dual wall high density polyethylene with powder coated steel hardware, and its page describes a controlled spring hinge lid that will not slam shut and a lockable lid (lock not included). Lifetime’s page does not publish dimensions, so the Amazon listing gives 5 feet long by 2 feet wide by 2 feet 2.5 inches tall on the outside and 57 by 20.75 by 23.75 inches on the inside. It has the smallest capacity of the three at 130 gallons. It is available on Amazon.
Check Price on Amazon →Our Take
For the most storage per dollar, the Keter Westwood is the pick. The Lifetime is a strong alternative if you want a longer warranty than the Keter at a similar price. The Suncast costs noticeably more per gallon, so choose it only if its lid design and finish appeal to you.

Frequently Asked Questions
What size deck box do I need?
For a typical patio set with four to six chairs, 100 to 150 gallons is enough for the cushions. Measure your cushions first and compare them to the interior dimensions of the box.
Are deck boxes waterproof?
Most are water resistant, not fully waterproof. They shed rain well, but water can get in during heavy storms or if the box is under standing water. Store cushions in a dry, breathable bag for extra protection.
Can you sit on a deck box?
Manufacturers design most large deck boxes to double as a bench. Keter says its box seats two adults, Suncast says the lid is reinforced for seating with a 300 pound lid weight capacity, and Lifetime says its box can be used as a bench. Check each manufacturer page for weight limits.
Can I lock a deck box?
All three manufacturers list a lockable lid, and none includes a lock. The Suncast lid is pad-lockable.
