Deck Box with Cushion 100 Gallon Waterproof Resin Storage Bench

In this review the Flamaker Deck Box with Cushion is examined as a practical outdoor storage solution for homeowners who need a weatherproof, multipurpose bench. The bottom line: if you want a large, affordable storage chest that doubles as extra seating and keeps cushions or pool toys dry, this 100 gallon resin deck box delivers solid value. It is best for patios, decks, and poolside areas where waterproofing, UV resistance and simple portability matter more than premium materials or heavy commercial use.

Key Features

• All-Weather Material: The resin construction is waterproof and UV resistant, which helps protect the exterior from fading and keeps contents dry through rain and sun exposure.
• Extra Seat with Cushion: The thickened cushion provides comfortable occasional seating and the resin base supports up to about 150 lb, adding practical function to storage.
• Metal Reinforcement: A metal bar in the lid reduces bending under sun and rain so the top remains usable as a seat and resists warping over time.
• Lockable Lid: The lid includes a locking hole so you can secure the box and protect stored items from loss or casual access.
• Easy Mobility: Handles on both sides allow two people to move the box when needed, making it easier to reposition on a deck or patio.
• Spacious Capacity: The 100 gallon interior fits cushions, pool accessories, gardening tools and other bulky outdoor items for clutter-free storage.

Who It's For

This deck box is a good fit for homeowners or renters with moderate outdoor storage needs who want an affordable, weatherproof container that also functions as occasional seating. It works well on patios, porches, balconies, and pool decks where keeping cushions and toys dry is a priority.

It is less suited to buyers who need industrial-strength, heavy-duty commercial storage or who expect the product to withstand constant, heavy weight or extreme impact. Some customers have reported occasional damage in transit, so those wanting a premium warranty experience may want to consider other options.
