      What the Sleep Expert thinks...

      "Pairing Geltex®’s breathable, pressure‑dissolving foam with PostureTech CS springs, this mattress offers buoyant support that cools as it cushions.The plush pillow‑top is by far the star of the shop, amping up surface softness for a snuggly sleeping environment. EdgeGuard keeps the comfort area generous, making it perfect for sleepers who want to spread out and get comfy with a cloud-like sensation."
