Quick answer
The Keter Signature 150 gallon deck box holds roughly 20 cubic feet—enough for 8-10 patio cushions, a full set of garden tools, or 4-5 standard camping chairs. It also doubles as a sturdy bench for two adults.
Why 150 gallons matters for your patio
A 150 gallon deck box isn't just about volume—it's about the kinds of items you can store without cramming. This size fits bulky, odd-shaped gear like folding chairs, large planters, or kids' outdoor toys that smaller boxes can't handle. The trade-off is that it takes up more floor space, so measure your patio before buying.
Seating vs. storage trade-off
The Signature 150 doubles as a bench, but using it for seating means you can't pile items right under the lid. If you plan to sit on it regularly, leave the top layer clear or store only soft items like cushions. For pure storage, you can fill it to the brim.
How to decide if the Signature 150 is right for you
- Measure your items first: Check the longest and widest item you plan to store—like a 40-inch chair or a 30-inch planter. The Signature 150's interior is about 55 x 26 x 25 inches. If your item fits those dimensions, the box works.
- Consider seat height: The box is about 25 inches tall, which is standard bench height. If you're taller than 6 feet, you may find it a bit low for comfortable seating. Add a cushion if needed.
- Prioritize weather resistance: The Signature line uses UV-resistant resin that won't fade or crack in sun or rain. If your box sits in direct sunlight all day, this finish saves you from replacing it in a few years. For covered patios, a less expensive box might work, but for exposed spots, the Signature's durability is worth the investment.
