Description

Precision Protection for Angled & Tapered Designs
Trapezoidal or prism-shaped furniture adds bold geometry to patios and modern outdoor settings—but it’s notoriously hard to protect. Standard rectangular covers leave excess fabric along the sides or fail to align with the front slope, leading to pooling water and wind lift.

OurCustom Trapezoidal Prism-Shaped Covers solve this by matching the incline and taper of your piece exactly. The angled pattern hugs the structure’s lines for a sleek, stable fit that looks as good as it performs.

Why Choose ZIPCovers Trapezoidal Prism Covers?

Industry-Exclusive 18 oz Fabric Strength:At 18 ounces per square yard, our PVC-coated polyester far exceeds typical outdoor fabrics. It resists abrasion, UV exposure, and water penetration while maintaining flexibility year after year. Lighter 8–12 oz fabrics can’t compete in longevity or structural integrity.
Precision-Angled Engineering:Each cover is drafted to your specificHeight, Total Depth, Width, Front Height, and Depth of Top. This ensures that every panel meets at the exact slope your furniture demands—no bulging at the base or tension at the edges.
Ventilation Built for Slope Stability:Integrated vents allow airflow beneath the cover while preserving the trapezoidal seal. This prevents pressure buildup under angled surfaces and keeps internal temperatures regulated.
Wind-Secure Drawstring System:Rust-proof grommets and adjustable drawstring keep the cover anchored, even on windy decks or rooftops.
Decade-Long Durability Promise:Every trapezoidal prism cover is backed by ZIPCovers’10-year warranty, reflecting true, tested endurance—not marketing claims.

Frequently Asked Questions

Furniture with angled or tapered sides—like modern benches, sloped consoles, geometric loungers, or architectural seating blocks—benefits most from this design. These covers replicate the slope and angle for accurate protection.

Total Depth” measures the entire side from back base to front base, while “Depth of Top” measures the top plane along the slope. The difference defines the exact angle of your furniture’s incline.

Yes. The 18 oz PVC-coated polyester withstands abrasion and moisture, making it ideal for protecting hard-surface materials like concrete, composite wood, or stone benches.

Absolutely. Provide accurate measurements for each dimension, and our patterning process accommodates variations in slope or uneven front/back ratios.

No. The slanted geometry combined with waterproof fabric encourages natural runoff. Water slides away from the high-back area toward the front without pooling.

Yes, if your boxes or planters have sloped sides or lids. The trapezoidal prism shape ensures a snug contour that prevents debris and moisture from entering around the edges.

Let it air-dry completely after cleaning, then fold loosely to avoid creasing. Store in a cool, shaded area—avoiding sharp bends—to extend fabric life.
