Our take on the RV Narrow King 80 L x 70 W x 8 Thick

This is an 8-inch foam mattress cut to RV narrow king size, 80 by 70 inches, for camper and motorhome beds that are not standard king width. The core is a dense foam Comfort Core with CertiPUR-US certification, aimed at firm support and ache relief rather than plush sink-in comfort. It suits RV owners replacing a worn factory mattress who want a firm, simple foam slab that fits a tight bunk footprint. Against innerspring and hybrid RV mattresses it is lighter and has no coils to poke through, but it offers no cooling layer, no edge support and no motion isolation beyond what plain foam gives.

Questions and answers

Will it fit my RV's narrow king bed?
It is built to 80 by 70 inches, the narrow king size used in many campers and motorhomes. Measure your platform and any slide-out clearance before ordering, since standard king sheets will be too wide.
Is this mattress firm or soft?
It is a firm foam mattress. The dense Comfort Core is designed for support and ache relief, not a soft, sinking feel.
Do I need a box spring under it?
No. Foam mattresses are usually placed on a flat, solid RV platform or a slatted base with close spacing. A box spring adds height that may not clear slides or bunks.
How thick is it, and does that matter?
It is 8 inches thick. That is on the thin side for an adult side sleeper, so heavier sleepers may want a thicker topper or a deeper mattress.
What is CertiPUR-US certification?
It means the foam meets limits on certain chemicals and emissions and is made without ozone depleters or heavy metals. It is a materials standard, not a comfort rating.
Can I use regular king sheets on it?
No. A standard king is wider, so the sheets will be loose. Look for RV narrow king or 70-inch-wide sheets.
