13 standard sizes. Plus whatever else you need.
We don't stock mattresses — every single one is cut to your size at our South Carolina facility. Our 13 standard dimensions cover the vast majority of RVs and home beds. Everything else is a custom build at the same quality.

Not a standard size? That's our normal.
A big share of our orders include at least one custom modification — an odd dimension, a rounded corner, a notch for a slide-out. Since nothing sits on a warehouse floor, "custom" isn't a special order. It's Tuesday.
We build any size to the whole inch, and we add rounded corners, notches, and hinges to match your platform. Here's what that looks like.
Enter your size. We cut to it.
Our 3D Custom Builder walks you through measurements, corner shapes, and modifications step by step. Same mattress, shaped to your bed.
Launch Custom BuilderMeasure your platform in 3 minutes.
Pull the old mattress out. Measure the platform — not the old mattress (foam compresses, covers shrink). Round down when in doubt; slightly tight is easier to live with than too big.

1Width & length, corner to cornerMeasure the platform at its widest and longest points. If the platform is uneven, measure both sides and use the smaller number.
-
2Radius on any rounded cornerIf any corner is curved, trace the curve on a piece of paper or measure the radius from the corner inward. A 2" or 3" radius is typical.
-
3Notches, cutouts, and thicknessNote any notches for wheel wells or posts (width × depth). Also check clearance above — we build 6", 8", and 10–11" profiles.
Need a custom corner?
Radius, angle, or notch — if your bed has a rounded corner, a diagonal cut, or a cabinet cutout, we match it exactly. Here's how to measure yours.
Need a hinge?
Slide-out clearance, easier storage access, or a Murphy-bed fold? Most hinges let the foot flip up when a slide comes in. We add a clean hinge wherever you need it.
