What are the thickest gel memory foam mattress options available?

The Nectar Luxe 14in Memory Foam Mattress is a medium-feel all-foam mattress designed for extra cradling and contouring support, with triple the pressure-relieving memory foam compared with the Nectar Classic. It also uses enhanced cooling for a more refreshing sleep surface, including a cool-to-the-touch design and more than double the cooling fibers. It suits people who want a thicker, more conforming memory foam feel and improved temperature comfort.

This 14in mattress uses three layers of hypoallergenic, gel-infused memory foam for pressure relief and temperature regulation. The Firm feel suits sleepers who prefer a supportive, stable all-foam surface.

This medium-feel mattress has a 14 in, three-layer all-foam design with gel-infused memory foam, air-channel foam, and a durable support base. Its cooling materials and motion-isolating foam make it suitable for sleepers who want pressure relief and fewer disturbances from a partner.

The Saatva Contour5 is a cooling memory-foam mattress with a CoolVent™ System and a Lumbar Zone® PCM Matrix positioned at the center third for temperature regulation and lumbar support. It's available in two firmness levels (Medium 5-7/10 and Firm 8/10) with an all-foam, body-hugging feel and strong motion isolation for couples.

This firm luxury hybrid mattress is 15 in thick and combines high-density foam, two microcoil layers, zoned pocketed coils, and a DuraDense foam base. Its GlacioTex Elite cover and optional CoolForce Layer are designed for hot sleepers, while the dense foams and microcoils help reduce partner motion.
