      What the Sleep Expert thinks...

      "PostureTech CS springs deliver a graduated response, but it’s the built‑in PowerPack that really locks in lumbar support, holding your hips level all night. EdgeGuard protects the perimeter, and a hand‑tufted finish cements the Ortho Plus Gold’s robust, firm feel for sleepers who crave orthopaedic stability."
