Which is better for a short queen RV bed?

Both come in short queen. The CopperFlex adds 21 size options and three heights, so it fits more unusual RV layouts. The Celestial Sleep is a single 10-inch short queen.

The CopperFlex backs its coils and foam with a limited lifetime warranty, which suggests a longer service life. The Celestial Sleep lists no warranty, and all-foam mattresses at this price typically soften sooner.

Is the CopperFlex worth the extra money?

If you sleep hot, want edge support or need a trial period, yes. If the mattress is for occasional RV use and budget is tight, the Celestial Sleep covers the basics for far less.

Both use cooling tech. The CopperFlex wicks moisture through copper-infused foam, but its cool-to-touch cover is only on the 14-inch model. The Celestial Sleep uses gel beads and a heat-wicking cover.

Which is easier to move in a Murphy bed?

The Celestial Sleep. The CopperFlex is noticeably heavier than a foam mattress and adds height, which buyers flag as a problem for Murphy beds.

Which is better for side sleepers?

The CopperFlex's medium-firm quilt foam relieves pressure while coils support the hips and shoulders. The Celestial Sleep's gel memory foam conforms more, which some side sleepers prefer but others find too soft.
