The height of the Plank Firm mattress is 10.25”. An illustration of the mattress with details for each layer is found on the product page, along with a full product description.

The flippable design of the Plank Firm mattress allows you to choose your ideal firmness level. A .75” quilted top layer, patterned with continuous stitching, ensures zero loft for an ultra-firm sleep experience. Or, flip the mattress, and a .75” quilted layer, patterned with tack-and-jump stitching, creates minimal loft for a firm sleep experience. Next level firmness can be achieved by eliminating the mattress altogether and sleeping directly on the floor. You will, however, lose some of the pressure point relief that comes with sleeping on an actual mattress.

Extra firm mattresses are highly favored by back and stomach sleepers for their superior support, crucial for maintaining proper spinal alignment and preventing overarching of the spine, especially in these sleeping positions. By providing a firm surface, they distribute body weight evenly, reducing pressure point pain and promoting restful sleep. To enhance comfort without compromising firmness, incorporating a cooling mattress topper can be transformative, regulating temperature and wicking away moisture for night sweats and hot sleepers. This combination of an extra firm mattress with a cooling topper offers optimal support for spinal alignment and enhanced comfort, ideal for those prioritizing back health and seeking relief from pressure point pain while ensuring a cooler and more comfortable sleep surface.
