Plank Firm
From: $524.30
The Plank Firm is a flippable all-foam mattress built for sleepers who want serious firmness and minimal sink. One side offers a Firm feel while the other delivers an Extra Firm, ultra-flat sleep surface for maximum support. Its dense foam construction helps keep the body lifted and aligned, making it an excellent choice for back and stomach sleepers who prefer a much firmer mattress.
