Measuring Guides

How to Measure Foam — Expert Guides

Getting accurate measurements is the key to a perfect fit. Follow our step-by-step guides for the most common foam applications.

How to Measure Sofa Cushions

Remove your existing cushion and measure length, width, and thickness. For tapered backs, measure front and back widths separately.

1Remove cushion from sofa and place on a flat surface
2Measure width (left to right) at the widest point
3Measure depth (front to back) at the longest point
4Measure thickness from top to bottom
5Note if the cushion tapers — measure both front and back widths

💡 Pro Tip: If your cushion has lost its shape, measure the sofa cavity instead for the most accurate fit.

How to Measure Chair Seat Foam

For dining chairs, office seats, and occasional chairs. Accurate measurement ensures a snug, professional fit.

1Remove existing pad or foam if present
2Place paper/cardboard on the seat base and trace the outline
3Measure the traced shape at its widest and deepest points
4Decide on thickness — typically 2-4 inches for seats
5Select the closest shape in our calculator

💡 Pro Tip: For chairs with a curved front edge, choose our 'Rounded Edge Rectangle' shape.

How to Measure Boat & Marine Cushions

Boat seating often has unusual shapes. Here's how to get precise measurements for a perfect fit.

1Create a cardboard template of each seat area
2Label each template clearly (port, starboard, bow, etc.)
3Measure length, width at widest point, and any angles
4Note if there are cutouts for posts or fittings
5Choose the closest shape or contact us for a custom quote

💡 Pro Tip: For complex marine shapes, use our Chat & Order feature — upload a photo or sketch for instant pricing.

How to Measure Campervan Mattress Foam

Campervan beds are rarely standard sizes. Follow these steps for a perfect rock-and-roll or fixed bed mattress.

1Measure the bed platform at its longest and widest points
2Check for wheel arch cutouts — measure their position and size
3Note any curved corners or tapering at the foot end
4Choose thickness: 3" for occasional use, 4-6" for regular sleeping
5Consider memory foam topper for extra comfort on longer trips

💡 Pro Tip: For VW T5/T6 rock-and-roll beds, our L-shape calculator handles the standard layout perfectly.

How to Measure Window Seat & Bay Window Foam

Window seats and bay windows need precise angles. A paper template makes this easy.

1Lay newspaper or lining paper across the entire seat area
2Trace the exact shape including corners and angles
3Measure the longest width and deepest depth
4Measure any angles from the straight back edge
5Standard thickness: 3-4 inches for comfortable seating

💡 Pro Tip: Use our 5-sided or 6-sided shape calculator for bay windows. Upload your template to Chat & Order for complex shapes.

Need help with an unusual shape? Our AI assistant can help you measure and price any foam shape.
