If your motorhome or luxury fifth wheel has a king bed, you get the best of both worlds — residential-length sleep with RV-friendly materials. But “RV King” isn’t the same as a household king, so buying the right one takes a little care. Here are the best RV King mattresses of 2026, plus exactly how the sizing works so you get a proper fit.
RV King sizing: 72″ or 76″ wide
An RV King is typically 72 inches wide by 80 inches long, though some rigs fit a full 76-inch residential-width king. Both are full residential length (80 inches), so tall sleepers are comfortable — the difference is width. Measure your bed platform before buying: a 72-inch RV King and a 76-inch standard king are four inches apart, which is the difference between a snug fit and a mattress that won’t close the slide-out. See our full RV mattress sizes guide for the complete breakdown.

Best overall RV King: 10-inch memory foam or hybrid
For most rigs, a 10-inch RV King memory foam or hybrid is the sweet spot — genuinely comfortable, but light and flexible enough for RV use. Memory foam contours and isolates motion (nice when one partner gets up early for the drive); a thin hybrid adds airflow and a little bounce. Confirm the height clears your headroom and any under-bed storage.

Best cooling RV King
Big rigs still get hot and stuffy at night, so if you sleep warm, choose a gel-infused foam or a thin hybrid RV King with a breathable coil layer. Both sleep cooler than dense factory foam. Our cooling RV mattress guide has more on beating the heat on the road.

How to choose your RV King
Measure first — confirm whether your platform takes a 72-inch or 76-inch width, and check the available height. Then pick your feel: foam for quiet, motion-isolating contouring, or a thin hybrid if you sleep hot. Insist on CertiPUR-US certified foam, and keep the height RV-appropriate (usually 10 inches or less) so the bed works with your headroom and storage. Get the width right and the rest is easy.
Frequently asked questions
Is an RV King the same as a regular king? Not always — many RV Kings are 72 inches wide versus a household king’s 76 inches, though some rigs fit the full 76. Both are 80 inches long. Measure to confirm.
How thick should an RV King mattress be? Usually up to 10 inches for a main bed, less if headroom or a slide-out lid limits clearance.
Do RV King mattresses ship in a box? Yes — most foam and hybrid RV Kings ship compressed, so you can carry the box into the rig and unroll it.
Can I use a regular king mattress in my RV? Only if your platform is the full 76 inches wide and the height/weight work. Many RV kings are narrower, so measure before assuming.
The bottom line
An RV King gives you residential-length sleep in a rig — as long as you nail the width. Measure your platform for a 72- or 76-inch fit, choose a 10-inch CertiPUR-US foam or thin hybrid (cooling if you camp warm), and confirm the height clears your storage and headroom. Get the size right and your motorhome sleeps like home.
