What size deck box do I need?

For a few seat cushions and pool floats, 90–135 gallon boxes (like the Keter Kentwood, Lifetime 130, or Devoko 100) are usually enough. For full patio sets, deep cushions, and bulky equipment, buyers tend to step up to 230–320 gallon models. Reviewers frequently note that listed gallon ratings run optimistic, so size up if you're between capacities.
