The Plank Firm Luxe 13" Hybrid Mattress is engineered for sleepers who demand maximum firmness, exceptional spinal alignment, and zero sink. Designed with a flippable dual-sided construction, this luxury hybrid mattress offers two firmness options in one—Firm on one side and Ultra-Firm on the other—allowing you to customize your sleep surface as your comfort needs change.
At its core, the Plank Firm Luxe features up to 961 individually encased coils, delivering enhanced responsiveness, superior edge support, and excellent motion isolation. High-density comfort foams work in tandem with the advanced coil system to provide pressure relief without sacrificing firmness, making it an ideal choice for back sleepers, stomach sleepers, and anyone seeking a firm mattress for back support.
Inspired by the flat, supportive feel of traditional sleep surfaces like Tatami mats, this mattress promotes proper spinal alignment and helps reduce lower-back strain—perfect for those who prefer a no-sink, on-top-of-the-bed sleep experience.
For hot sleepers, an optional cooling cover is available to help regulate temperature throughout the night. The Plank Firm Luxe is also available in RV mattress sizes, offering uncompromising firm support whether you’re at home or on the road.
