Description

Eight-Sided Precision. One Seamless Fit.
Octagonal furniture or fixtures elevate outdoor design—but their multi-cornered shape makes protection a challenge. Standard square or round covers leave awkward gaps, causing water collection or uneven tension.

OurCustom Octagonal Prism Covers are engineered to fit every edge, angle, and surface of your furniture’s unique geometry. Using six precise measurements, we pattern each piece to match your octagonal layout—providing clean symmetry and full-edge protection.

Designed for years of performance, it withstands intense climates without fading or tearing.
  • Precision Octagonal Craftsmanship:Each cover is tailored using your exactHeight, Depths, Widths, and Corner Depth to align perfectly with all eight faces of your furniture. This ensures seamless corner fitting and eliminates loose areas or bulging fabric.
  • Ventilated, Weatherproof Engineering:Strategic air vents maintain airflow beneath the cover, reducing humidity buildup without compromising waterproofing. The angled sides promote natural runoff, preventing water accumulation on top.
  • Wind-Secure & Easy to Manage:Rust-free grommets and an adjustable drawstring hem create a secure, wind-tight fit. Reinforced side handles make removal simple and controlled, even for larger covers.
  • 10-Year Warranty Protection:Each cover is backed by a10-year warranty, ensuring long-lasting protection and reliability through every season.

This was our first time ordering a custom cover for the long chairs on the deck. The loungers stay by the pool all summer and get a lot of sun. The inside of the cover feels smooth and does not catch on the furniture. Even around the arms and back the fit stays smooth and neat. I appreciate that the final product matched what was described when we ordered. The order arrived faster than the estimate shown at checkout.
