Achieve improved sleep posture and spinal alignment with AlignSupport® Coil's unique geometry that evenly distributes your body's weight.
With advanced AlignSupport® Coils that spring back to their original shape, you'll enjoy responsive comfort and steady support as you move through the night.
Twice-tempered AlignSupport® Coils deliver reinforced durability, so your mattress keeps its shape and support, year after year.
The unique ComfortCore™ layer targets your body's heaviest areas to deliver superior pressure relief where you need it most.
The blend of durable foam and ComfortCore™ creates a firm mattress with a surprisingly plush, luxurious feel.
UniCased® edge support lets you stretch out to the very edge, with a strong casing that keeps springs secure and prevents roll-off.
Endorsed by Allergy UK, Sealy's ProShield® helps keep allergens at bay for a cleaner, fresher sleep.
The SmarTex® cover wicks away moisture to help regulate your temperature throughout the night.

Dual layers of high density foam are placed at the centre of the mattress to enhance the support of the spring system and provide a consistent firm feel.
Strong and durable AlignSupport® springs are twice tempered to offer strong support. These springs are designed to evenly distribute your weight and deliver responsive support night after night.
Edge to edge support with a unique design as durable foam is placed around the spring unit. This reinforces the border of the mattress and reduces a 'roll off' sensation.
Adding an extra touch of comfort, the top layer of this mattress features a foam microquilt. By stitching the knitted cover to a layer of foam, this technique results in a cushioned feel.
This layer of foam moulds to your unique shape, lifting weight off the heaviest parts of your body to deliver soothing pressure relief.


A special treatment that helps to dispel allergens for a healthier sleep space that is Allergy UK approved.
Knitted cover is soft to touch and features SmarTex® treatment that is designed to wick away moisture for a fresher feel.

Try this mattress at home for 60 nights with our free Comfort Trial. If it's not quite right, you can exchange it easily.
When does the trial start? - Your 60-night Comfort Trial starts the day your new mattress arrives.
What do you need to do? - Sleep on your new mattress for at least 30 nights, using a mattress protector. This gives your body time to adjust and allows the mattress to settle.
How do you exchange? - After 30 nights, if it's not quite right, simply get in touch to exchange it for another mattress of the same size - we'll collect your old one when we deliver the new.
Want to upgrade? Simply pay the difference.
If you choose a lower-priced option, the original cost will stay the same.
