What the Sleep Expert thinks...
"PostureTech CoreSupport springs sense your weight, firming under heavier areas while staying comfortably responsive elsewhere. This makes this mattress ideal for improving your posture as you sleep, and I particularly love how these springs adjust quickly to your movements to maintain the most consistent level of support. Paired with a hand‑tufted surface and breathable polyester comfort fibre, the Ortho Plus Essential delivers dependable, medium‑firm support that keeps your spine aligned and the mattress feeling fresh night after night."
