A deck box keeps cushions, pool toys and garden tools out of the sun and most of the rain, and many double as a bench. Most are molded resin in the 100 to 150 gallon range, and the differences are in how the lid opens, how well the box sheds water, and what the maker says the lid can hold.
We compared deck boxes on interior capacity and dimensions, material and wall construction, lid hinge, stated seat capacity, locking and warranty. If you want a backrest too, see Best Outdoor Storage Benches, or browse the Deck Boxes & Outdoor Storage category.

How to Choose a Deck Box
Capacity and Interior Size
Gallon figures tell you volume, but a long seat cushion needs length too. Compare the interior dimensions with the largest item you plan to store, where the maker lists them.
Water Resistance
Most deck boxes are water resistant rather than waterproof. Lifetime, for example, says its storage boxes are not waterproof. Place the box on level ground, keep the lid closed, and store cushions dry.
Lid and Seating
Gas struts and controlled hinges stop the lid from slamming. If you plan to sit on the box, use the maker's stated seat or lid capacity, and do not exceed it.
Safety
Lock the lid if children are around, and do not let children play inside or climb into a storage box.
How We Evaluate Deck Boxes
For this guide we compared deck boxes on interior capacity and dimensions, material and wall construction, lid hinge, stated seat or lid capacity, locking and warranty. We read each maker's specifications and left out listings that repeated another seller's description. Ratings appear only where our product data includes a rating with a review count. We did not handle these boxes ourselves, every figure comes from the maker's listing, and we never repeat a waterproof claim as our own.
Variants of one listing count as a single product, and we would rather list a few strong picks than pad the list. Our full process is on the How We Review page.
FAQ
What size deck box do I need?
Measure the largest cushion or item you want to store and compare it with the box's interior dimensions, not only its gallon rating.
Are deck boxes waterproof?
Most are water resistant. Water can get in through seams and the lid gap in heavy rain, so store items dry.
Can you sit on a deck box?
Many are designed as benches. Use the maker's stated seat or lid capacity.
Final Verdict
Keter's Westwood is our top pick for its 150 gallon capacity and two-person seat. Lifetime has the sturdiest dual-wall build and published interior dimensions, and Suncast makes a US-built box with a stated 300 lb lid.
Devoko adds gas struts, EAST OAK snaps together without tools, and Quictent offers a 2-year warranty.
