On a scale of 1 to 10, the firm side of the Plank Firm mattress ranges between 7.5-9. This ranking is slightly above a traditional firm mattress. The ultra-firm side ranges between 9.5-10.5 — meaning it’s the firmest, flattest sleep surface on the market. To put that in perspective, next level firmness could only be achieved by sleeping directly on the floor with no pressure point relief.

The weight added from the Cloud Pillow Top varies based on the mattress size. Please see below for the added weight for each mattress:

The height of the Plank Firm is 10.” An illustration of the mattress with details for each layer is found on the product page, along with a full product description.

Any mattress foundation with slats no more than 3 inches apart will work well with any RV mattress. While a mattress foundation is not necessary, please be sure that the mattress rests on a surface with minimal to no flex.

If you prefer a foundation, please see our RV Mattress foundations here.

The Plank Firm and Plank Firm Luxe mattresses are designed with varying firmness levels on either side of the mattress and can be flipped to customize your sleep experience.

Several factors can contribute to a mattress’s firmness level—including foam density, transition foams, and coil systems. The product specifications for each mattress, as well as unique features and benefits, can be found on the product page. Mattresses that come in soft, medium, and firm level options display a firmness scale on the same product page to help you determine the right level for you.
