Clearance Adjustable Base Compatible Yes Green All Mattresses

Clearance mattresses are marked down to clear — floor models, discontinued lines, and overstock at our deepest discounts while quantities last. Compare every clearance option below by brand, type, and price.
These mattresses are built to flex with adjustable bed bases — bending smoothly at the head and foot without damage — so you can raise, recline, and find your ideal position. Compare every adjustable-base-compatible option below by brand, type, and feel.
