Buying Guide
What size should I choose?
Consider the total amount of items you store and how often you access them. Large capacity boxes (100β160 gallons) suit cushions, pool toys, and seasonal gear, while 30β71 gallon models fit small patios or balconies with limited space.
What materials matter?
Resin and polypropyleneConstruction resist fading, cracking, and rust. Wood-look textures provide aesthetic appeal, while smooth plastics may be easier to clean. UV resistance helps prevent sun damage over time.
Do I need seating or a table?
Some models integrate seating or a side table, increasing utility in tight outdoor areas. The trade-off can be depth or interior height, which affects what you can store.
How important is security?
Lockable lids add security for valuables and deter pests. If security is important, verify lock compatibility and lid strength before purchase.
How weatherproof is it?
Look for models with waterproof or water-resistant seals and ventilated interiors to prevent mold. UV protection helps maintain color and material integrity across seasons.
Which is best for a specific space?
Small spaces: pick compact models like the Marvel 71 Gal or City 30 Gal. Large decks: consider the Westwood 150 Gal or ATMELT 160 Gal for maximum storage and seating capabilities.
