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."

Purchased to replace a 9 year old Sealy ortho mattress. This is a well made mattress. After the first week, it seems comfortable and we are sleeping well. My only negative is there are no side handles which my old mattress had. So rotating the mattress is not as easy.

I am so happy with my new Sealy. I always buy Sealy. So comforting, supportive and sleep-inducing. The best mattresses in the World. And my new King Size with an extra six inches makes all the difference.
