Support system
With a blend of Sealy's own PostureTech Core Support springs and a cosy layer of MemorySense foam, this mattress provides you with soothing pressure relief.

An innovative spring design from the specialists at Sealy that uses unique shapes and varied tension to provide excellent full-body support and pressure relief.

Memory foam creates a cushioned feel by cradling to your unique shape. Enhancing the remarkable comfort, the foam has a sumptuous feel, delivering a cosy sleep.

Durable edge-to-edge support provides a maximised sleeping surface for a more secure sleep. Sit and lay comfortably right to the very edge with zero 'roll-off' sensation.

Offering a soothing night's rest by evenly distributing your body weight across the mattress. The pressure point relief provides the ultimate relaxation needed for a deep slumber.

A sumptuously soft finish that provides additional cosiness and warmth. Knitted covers enhance airflow and are incredibly breathable. So, you can enjoy a cooler snooze.

Stitched into the mattress border, turning handles are there for easier moving and turning. When caring for your mattress, simply use the handles provided for ease of use.

Verified Purchase
For starters super quick delivery really surprised me, I suffer with back problems and appear to have been sleeping somewhat better and more comfortably since changing to this mattress (don't wake up half as achy) I still feel its early days to say its exactly what I need but all positive feedback at the moment.
Verified Purchase
Great value for money as I bought this on a Black Friday sale. The depth of the mattress works in a larger room. Comfortable and supportive in position but a bit soft when moving
