Know before you buy
The box is designed to be weather-resistant and will protect your cushions from rain and debris. However, it is not airtight or hermetically sealed, so we recommend placing it in a covered area if you live in an environment with extreme, driving rain.
Some assembly is required upon delivery. The box comes with all necessary stainless steel hardware, and you will need basic tools to complete the setup.
Yes, the interior dimensions are spacious enough to accommodate up to three sets of standard deep-seating cushions. As long as your cushions fit within the 58-inch width and 23-inch depth, they should store easily.
The HDPE recycled plastic is engineered for outdoor longevity and is highly resistant to fading. It is designed to maintain its color integrity even when exposed to harsh sunlight over many years.
This specific model is intended for residential use only and carries a 20-year residential warranty. It is not rated for commercial applications, which are covered by a separate 5-year warranty.
The box is exceptionally low-maintenance. You can simply clean it with mild soap and water as needed to remove dust or pollen; no staining, painting, or waterproofing treatments are required.
