The Diamond is the top of the Stitchco line — a smooth-top hybrid with our most advanced cooling system. Named for the Arkansas state gem (Arkansas is home to the only public diamond mine in the U.S.), it pairs a sleek 14" smooth-top profile with premium materials throughout.
Its standout layer is a copper-, graphite-, and silver-infused memory foam that dissipates heat, stays fresh, and delivers exceptional pressure relief, backed by responsive Serene® hybrid foam, a latex lumbar support layer, and the 8" zoned pocketed coil.
