Measure before you order
Record the length, width and thickness of each cushion separately using a tape measure. Check the cover seam to seam without stretching it, and compare it with the existing insert. A flattened old insert may not represent the original size. Do not automatically add extra thickness or rely on a phone measurement for a made-to-measure order.
For a boxed cover, thickness is the depth of the side panel, not the diagonal across the cushion. For curved, tapered, T-shaped or L-shaped cushions, record every relevant edge and send a labelled drawing if the calculator template does not match. Confirm uncertain measurements before payment.

Choose the foam for your cushion
The calculator offers Deluxe Soft, Deluxe Medium and Deluxe Firm upholstery foam. Tell us whether the cushion is a seat or back, its thickness, how it will be used and your preferred feel if you need help choosing. Density and firmness are different properties; a grade name alone does not guarantee a particular feel in every cushion.
Compare foam grades and firmness or ask us about your cushion.
Check quantity and extras
Enter the physical number of cushions required. Measure matching-looking cushions separately before assuming they are identical. Dacron and stockinette are optional extras in the calculator. Confirm the fit with your existing covers before choosing a wrap.
This ordering route is for foam inserts. Do not assume replacement fabric covers or upholstery work are included in the foam price.
Fit your new inserts
Check the specification before removing or forcing a cover over the new foam. Work gradually and avoid straining the zip or seams.

Price and delivery
Your price depends on the dimensions, foam selection, quantity and extras. Use the calculator for your own specification rather than a price attached to another customer's size. Check delivery information and contact us before ordering if you need a particular arrival date.
