Custom Size RV Mattresses, Cut to the Inch

RV beds rarely match standard mattress sizes. Bunks run 28″ to 35″ wide, short queens are 74″ or 75″ long, and many platforms have a clipped corner for a wall, cabinet or wheel well. This builder lets you enter your exact width and length, add angled or notched corners, and see your price right away, so your new mattress fits the platform instead of hanging over it or leaving a gap.

Every mattress is made to order by Magic Sleeper, a family-owned mattress company in Pottstown, Pennsylvania that has been in the mattress business since 1979. Mattresses ship rolled in a box by FedEx Ground, usually within 1 to 2 weeks, and shipping is free.

Common RV mattress sizes

Size name Width × length
RV Bunk 28″ × 75″, 30″ × 75″, 30″ × 80″, 34″ × 75″, 35″ × 79″
Three-Quarter 48″ × 75″

Size names vary between RV makers, so always measure your own platform. An “RV Queen” in one camper can be an inch or two different in another.

How to measure your RV bed

  1. Take the old mattress off the platform. Old mattresses stretch and sag, so don't measure them.
  2. Measure the width of the platform from edge to edge.
  3. Measure the length from the head of the bed to the foot.
  4. Round to the nearest half inch. If you are between sizes, go a little smaller rather than bigger.
  5. If a corner is cut for a wall, cabinet or wheel well, measure how far the cut runs along the width (X) and along the length (Y) from where the square corner would be.

Angled vs. notched corners

An angled corner is a straight diagonal cut across the corner, common on bunks and beds that sit against a slanted wall. A notched corner is a square cut-out for a post, cabinet or step. You can add either cut to any of the four corners, and the drawing in the builder shows your mattress shape as you go. Each cut can be up to half the mattress width and half the length. For curves, radius corners or larger cuts, call us and we'll build it by hand.

Frequently asked questions

Can you really make an RV mattress in any size?
Yes. The builder takes any width from 20″ to 76″ and any length from 20″ to 84″, in half-inch steps, with angled or notched corners. If you need something bigger or a shape the builder can't draw, such as a curved corner, call us at 610-327-2322 and we'll quote it.
Which thickness should I choose?
Choose the 5″ all-foam mattress for bunks, kids' beds and dinettes, or anywhere headroom and weight matter. Choose the 8″ gel memory foam mattress for a medium-firm main bed. Choose the 10″ gel memory foam mattress if you have the height and want the plushest feel, closest to a home mattress.
How much does a custom RV mattress cost?
The 5″ all-foam mattress starts at $179, the 8″ gel memory foam at $299 and the 10″ gel memory foam at $375. Price depends on the size range, up to $295, $699 and $725 for the widest sizes. Each angled or notched corner adds $50. Shipping is free.
Does an odd size cost more?
No. Pricing goes by size range, so a 33″ × 74″ bunk costs the same as a 30″ × 75″ bunk. The only extra charge is $50 for each modified corner.
How long does shipping take?
Mattresses are made to order and usually ship within 1 to 2 weeks by FedEx Ground. They ship rolled in a box, which makes them easy to carry into a camper through a narrow door. Shipping is free within the US.
How do I measure for an angled or notched corner?
Imagine where the square corner of the platform would be. X is how far the cut runs across the width from that point, and Y is how far it runs along the length. For a notch, X is how wide the cut-out is and Y is how deep it goes.
Should I measure the platform or my old mattress?
Measure the platform. Old mattresses compress and stretch over time. If you are between sizes, round down slightly so the new mattress fits without bowing.
Do you make RV mattresses with springs?
Yes. The builder covers our all-foam and gel memory foam RV mattresses, but our showroom has many innerspring and hybrid mattresses that we can make in RV sizes. See all RV mattresses or call us for a custom size.
Where are your RV mattresses made?
Every custom RV mattress is made to order in the USA for Magic Sleeper, a family-owned mattress company in Pottstown, Pennsylvania since 1979.
