AlignSupport® spring technology
Anything that is built to last has good foundations, featuring the patented AlignSupport®, the Sealy Newton Posturepedic mattress has springs that have been cleverly developed to provide genuine, lasting body support. AlignSupport™ is a two stage spring that starts by sensing your shape as you wriggle into your comfortable sleeping position. It then provides you with deep-down, consistent support that’s personal to you since it responds to your body. Also, the entire spring unit is twice tempered, which means it’s twice as strong and durable. So, you can rest easy knowing this mattress has got your back. Literally.
UniCased® edge support
Cocooning the spring unit with interlocking keys is our UniCased® edge support. The keys have been precisely engineered to intertwine with the springs, securing everything in place and providing greater stability. Designed by Sealy’s team of experts, UniCased® allows you to benefit from a larger usable sleep surface, removing the “rolling off” feeling as you sleep, and offering dependable durability.
Latex ComfortCore™
Supporting the entire mattress, BasePlank is an inspired, unifying foundation that provides reliable structure from corner to corner. The Latex ComfortCore™ is positioned at the heart of the mattress and is designed to target your hips and lower back for tailored pressure relief. Combined with a double layer of Sealy extra firm foam, the Newton mattress is perfect for those who prefer a firmer, more robust feel. For those who prefer something a little less firm, it is also available in a Medium comfort rating, so we’ve got you covered.
Intelligent SmarTex® fibres
The technology is not the only thing that’s unique about this Sealy Newton Posturepedic Mattress. The premium quality fabric has been expertly designed and tested to create a look that’s uniquely Sealy Posturepedic. The fabric has been woven with SmarTex® to disperse heat away from the skin and regulate your temperature as you get that all-important shut eye.
And that’s not all, ProShield® technology protects against allergens and aims to keep your mattress clean and fresh throughout its life. Don’t just take our word for it though, ProShield® is endorsed by Allergy UK for added peace of mind.
At Sealy, it’s their mission to create mattresses that last, and that’s why all the Sealy Posturepedic mattresses, are handmade right here in Britain, and come with a 10 year guarantee. *Available as Zip & Link Mattress.
