Our AlignSupport® has been carefully constructed and evolved over time to be a two stage spring. First, it senses your individual shape as you rest into the mattress, followed by an instant response that applies deep-down, consistent support. Also, you can sleep soundly knowing that the spring unit is twice tempered which means it’s twice as strong and durable- impressive, we know.

Encompassing 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 our team of experts, UniCased® allows you to benefit from a larger usable sleep surface, removing the “rolling off” feeling as you snooze and offering dependable durability you can trust.

Underpinning the entire mattress, BasePlank is an inspired, unifying foundation that provides structure from corner to corner. Plus, the multiple air channels allow the mattress to breathe and circulate air with ease.

When you create something special, it’s important to treat it that way. That’s why we have used high quality fabric, expertly designed and tested to create a look that is stand-out. Complete with SmarTex® , the fabric works to disperse heat from the skin and regulate your sleep climate. There’s also ProShield®, keeping allergens at bay and offering a clean and fresh night’s sleep. And you don’t just have to take our word for it, ProShield® is endorsed by Allergy UK.

And if all of that wasn’t enough, the breathable air mesh border also contributes to natural airflow, allowing air to circulate through the mattress freely.
