Custom Shape Cushion — Irregular Hexagon & Diamond, Any Size & Fabric

Hexagon and angled seats never come in a standard size. Every gazebo bench, hexagon ottoman, window nook, and boat berth has its own angles, so off-the-shelf rectangles leave gaps or hang over the edge.

A Custom Irregular Hexagon Cushion — the six-sided, diamond-shaped pad — fixes that. You pick the exact dimensions, the foam firmness, and the fabric, and we build the six-sided shape to match your seat.

Why customers choose us:

• Exact fit: we cut to your top edge, widest point, bottom edge, and heights, not a rounded-off size
• Seat and back together: order matching pieces so the whole nook lines up
• Foam that lasts: choose the density for light seating or daily use
• YKK zipper covers: removable covers that unzip for easy cleaning
• Made for your scene: indoor upholstery or marine-grade fabric for a boat or fire pit

How to Measure an Irregular Hexagon (Diamond) Cushion

Measure three widths: the top edge, the widest point across the middle, and the bottom edge. Then measure two heights: from the top edge down to the widest line, and from the widest line down to the bottom edge. Add the thickness you want. If your shape is unusual, trace it on kraft paper and send us the template.

A Custom Diamond-Shaped Cushion is a six-sided cushion built to your exact measurements. It fits the angled, hexagon, and tapered seats that store-bought rectangles never cover. You give us the top edge, the widest point, the bottom edge, and the two heights, and we cut the shape to match.

Perfect for:

• Hexagonal gazebo benches, where a made-to-fit gazebo bench cushion follows each angled side
• Hexagon ottomans and poufs that need a firm hexagon ottoman cushion top
• Boat seating and pointed berths, from cockpit seats to a shaped v-berth cushion
• Fire pit surrounds, where a fire pit bench cushion wraps the angled seating
• Turret nooks and angled bay windows that call for a diamond or turret window seat cushion
• Building a straight-sided window nook instead? Start with our custom bay window trapezoid cushion

Every cushion can be made as a seat, a back, or both, so the whole nook matches. Send us your shape and we cut the foam to fit the first time.

This cushion fits any six-sided or tapered seat where a plain rectangle would leave gaps at the corners. If your seat is widest across the middle and narrows toward the top and bottom edges, the diamond shape matches it. To confirm the fit, measure the top edge, the widest point across the middle, the bottom edge, and the two heights, then send us those five numbers. Every cushion can be built as a seat, a back, or both, and works indoors or outdoors depending on the fabric you choose, so a single shape covers gazebo benches, hexagon ottomans, boat berths, and turret window seats alike.

This shape lands both indoors and outside, so the fabric catalogue covers both. A hexagon ottoman in the living room and a gazebo bench in full sun need different cloth, and both are here.

All fabrics are:

• Fade and UV resistant, so outdoor colors hold through the season
• Easy to wipe clean, for spills on an ottoman or splashes on a boat
• Moisture and mildew resistant, which matters near fire pits, pools, and open water
• Built to take daily sitting without thinning or pilling
• Offered in a wide range of solids and patterns to match any room or yard

For gazebos, boats, and fire pits, choose solution-dyed acrylic or marine-grade fabric. For an indoor hexagon ottoman or turret bench, soft upholstery weaves and velvets give a warmer look.
