The Conforma Gel mattress features three inches of 4 lb. gel-infused memory foam over a high-density moldable polyurethane support core, and it builds that core in graduated density zones, 23 ILD and 32 ILD on the Plush, up to 44 ILD on the Firm, so the mattress flexes evenly rather than creasing when an adjustable base is raised. A fire-retardant 420g circular knit cover wraps the memory foam layer, which delivers pressure-relieving, body-contouring comfort without trapping heat the way older foam mattresses often did. The gel infusion in the memory foam helps dissipate heat more effectively than standard memory foam, making it a better choice for sleepers who tend to run warm.

Craftsmen hand-assemble the Conforma Gel in Sugarcreek, Ohio as a single-sided mattress specifically engineered for adjustable bed frames, so it flexes and contours as you change position rather than fighting against the base. They select and test each foam layer for how well it performs under repeated articulation, not just under static weight, which is part of what sets a purpose-built adjustable mattress apart from a standard mattress placed on an adjustable base.

Monarch Rest backs the Conforma Gel mattress with its full 20-year limited warranty, and it pairs naturally with any of the brand’s adjustable foundations. If you want the deep pressure relief of memory foam combined with a mattress engineered to move with an adjustable frame, this is one of the most purpose-built options in the entire Monarch Rest collection.
