Layers	Perfect Fit Memory Foam, Personalized Comfort, Essential Support Foam	Quilted Top, TitanFlex™ Foam, High-Density Base Foam, Quilted Bottom.
Cover	Our premium stretch-knit fabric cover with spun poly fibers that’s breathable and durable with a soft feel.	The flippable design of the Plank 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 1.5" quilted layer, patterned with tack-and-jump stitching, creates minimal loft for a firm sleep experience.
Machine-washable cover	No	No
Ergonomic handles	No	No
Comfort	Our high-quality memory foam adapts to your body size, shape and sleep position to ensure a great sleep no matter which feel is right for you.	Engineered to reduce pressure on your circulatory system the Plank provides for better blood flow - and better lower back support, compelling you to inhale more oxygen while you snooze.
Support	Choose our soft layer for a cozier, more "in-the-bed" feel. Choose our firm layer for a sturdier, "on-the-bed" feel. Engineered to be highly durable and resilient. We’ve tested it, and we know it bounces back every time.	The Plank offers a firmer, flatter, flippable surface for a neutral spine position that's better for your back and posture overall. A 2" layer of our firmest transitional TitanFlex™ foam adds deep compression support. A 7" high density base foam ensures durability and stability for the life of your bed.
