Keep awkward triangular shapes covered – neatly and securely
Some furniture and equipment simply doesn’t fit into a standard rectangle. Our made to measure triangular outdoor custom covers are designed for those awkward, angled pieces – from sloping BBQs and outdoor storage to bespoke benches and machinery. Every cover is cut and sewn to your dimensions for a close, tidy fit that looks as good as it protects.

Premium waterproof fabrics in two protection tiers
Choose the fabric that matches how (and where) you use your outdoor space:

• Tier 1 – PVL 600D vinyl-coated polyester
  Tough, waterproof and easy to handle – ideal for everyday garden furniture in typical UK weather.

• Tier 2 – P500UV laminated 500D polyester
  Premium, UV-boosted fabric for year-round exposure, south-facing patios and coastal or windy locations.

Both options are:

• Fully waterproof and UV-resistant

• Tear-resistant with strong seam construction

• Easy to wipe clean with mild soapy water

• Suitable for garden furniture, equipment, storage and more

Simple measurements for a complex shape
The triangular cover follows the same numbering as our diagram (alt text: “diagram”):

1. Height – from the ground to the highest point of the triangle.

2. Side #1 – base side running along the front.

3. Side #2 – second base side running along the depth.

4. Side #3 – the angled side that completes the triangle.

Enter your measurements in cm following the dashed lines on the diagram. We add a small tailoring allowance so the cover slides on easily without looking baggy.

Tie-down options for windy spots
Customise how your cover secures in place:

• No tie-downs – simple drop-over for sheltered areas

• Elasticated hem – pulls the base snug all the way around

• Grommets & cord – tie to fixed points or legs

• Straps & buckles – extra security for exposed or high-value items

Each tie-down option is sewn to order as part of your cover.

Built for UK gardens, backed by real support

• Handmade to your exact triangular dimensions

• Neat finishing with reinforced stitching at stress points

• Designed to reduce flapping, pooling water and sun fade

• Friendly UK-based support if you’re unsure how to measure – just upload a photo and add notes at checkout

Give your awkward-shaped furniture or equipment the same smart protection as the rest of your garden.
