Description

Three Sides. Perfect Geometry.

Triangular and wedge-shaped furniture adds dynamic angles to outdoor spaces—but the three-sided geometry makes finding proper protection challenging. Standard rectangular covers leave corners exposed or create excess bunching, while attempting to modify generic covers results in gaps, stress points, and inadequate protection along the angled edges.

OurCustom Triangular Covers are engineered to match the exact dimensions of your three-sided furniture. Using four precise measurements, we pattern each cover to accommodate any triangular configuration—whether equilateral, isosceles, or irregular—providing seamless coverage that protects all three edges while maintaining the distinctive angular profile of your furniture.

Why Choose these Triangular Covers?

  • Industry-Exclusive 18 oz Fabric Strength: Our heavy-duty 18 oz PVC-coated polyester offers superior outdoor endurance. It's twice as thick as standard materials, resisting punctures, UV rays, and moisture while maintaining flexibility. Designed for years of performance, it withstands intense climates without fading or tearing.

  • Precision Triangular Craftsmanship: Each cover is tailored using your exact Height, Width, Depth, and Side #3 measurements to create perfectly proportioned panels that align with all three edges. This ensures the cover follows your furniture's unique angles without gaps, sagging, or excess material at the corners.

  • Ventilated, Weatherproof Engineering: Strategic air vents maintain airflow beneath the cover, reducing humidity buildup without compromising waterproofing. The triangular geometry naturally promotes water runoff along the sloped surfaces, preventing pooling, while the angular design helps deflect wind effectively.

  • Wind-Secure & Easy to Manage: Rust-free grommets and adjustable drawstrings create a secure, wind-tight fit around the entire three-sided perimeter. Reinforced side handles make removal simple and controlled, even for larger triangular covers.

  • 10-Year Warranty Protection: Each cover is backed by a 10-year warranty, ensuring long-lasting protection and reliability through every season.

Our Custom Triangular Covers are ideal for:

  • Wedge-shaped outdoor seating and corner loungers
  • Triangular fire pit tables and corner tables
  • Wedge planters and corner garden features
  • Triangular ottomans and modular seating units
  • Corner storage boxes and deck bins

Frequently Asked Questions

While a triangle has three sides, we need Height (vertical dimension), Width (front edge), Depth (front to back distance), and Side #3 (the angled edge) to accurately construct a 3D triangular cover. These measurements ensure we capture both the base footprint and the vertical coverage.
Yes. The four-measurement system accommodates any triangular configuration—whether your furniture has equal sides (equilateral), two equal sides (isosceles), or all different sides (scalene/irregular). The measurements capture your specific geometry.
Our covers work best with straight-edged triangular furniture. If your furniture has significantly curved edges, please contact us for a custom consultation to ensure proper fit.
Yes. The inner surface is smooth and non-abrasive, preventing scratches on glass tabletops, polished metal frames, or decorative triangular surfaces.
Triangular covers offer good aerodynamic properties. The angled edges help deflect wind, and the pointed geometry reduces wind catch compared to flat surfaces. Combined with the heavy 18 oz material and secure drawstring system, the cover remains stable even in strong winds.
Yes. Triangular covers are perfect for corner wedge pieces. Just measure the dimensions of the individual wedge unit to ensure accurate coverage. If your wedge connects to other sections, measure only the exposed triangular portion.
