Outdoor Storage Box 100 Gallon Deck Box - Waterproof Lockable Bench

Our review of the Flamaker Outdoor Storage Box 100 Gallon finds it best suited for homeowners and renters who need a low-maintenance, weatherproof solution for patio cushions, pool accessories and garden tools. The single biggest reason to buy is its combination of waterproof resin construction and a lockable lid that keeps contents dry and secure while doubling as a usable seat or side table. It is not a premium wooden chest, but for anyone who values utility, easy outdoor integration and good value, it performs very well.

Key Features

• All-weather resin: The molded resin and polypropylene body resists UV fading and keeps the interior dry in rain and snow for long outdoor use.
• Lockable lid: A lid with a built-in locking hole provides a simple way to secure items and protect them from loss.
• Metal reinforcement bar: A reinforcement bar in the lid prevents bending under sun and rain, keeping the top rigid and reliable.
• Air rod support: Slow-open air rods prevent the lid from slamming shut and reduce the risk of finger pinches while accessing stored items.
• Portable design: Two handles on each side and a relatively lightweight build make the box easier to move around a patio or deck.
• Multipurpose use: With a 100 gallon capacity and 150 lb seat rating, it serves as storage, a bench, or a side table in outdoor or indoor spaces.

Who It's For

This storage box is ideal for families with outdoor furniture cushions, pool owners who need a dry place for toys and accessories, and gardeners who want a weatherproof container for small tools. Its simple look fits porches, decks, patios and poolside areas where functionality matters more than decorative detail.

Shoppers who want finely finished wooden furniture, integrated shelving, or higher weight capacity for heavy-duty seating should look elsewhere; this model prioritizes weather resistance, light portability and secure basic storage over bespoke design or heavy commercial loads.
