New and exclusive, the Sealy Advantage 1550 Gel Pillowtop combines the best of traditional and modern technology to help you get the perfect night's sleep.

Tried and Tested

The unique “S” shaped dual coil provides around 40% more surface area than traditional open coil spring units means significantly better weight distribution, enhanced core support and optimum spinal alignment. Each row of springs operates independently, providing better stability and reducing motion transfer. When combined with the 800 pocket springs, this support system will help to promote perfect spinal alignment, will provide responsive support where your body needs it the most and will provide exceptional pressure relief to eliminate aches and pains which will reduce both tossing and turning and partner disturbance… perfect if you suffer from restless nights.

Sleep Science

New and improved geometry and a 4-sided Edge-Guard system around the entire perimeter of the mattress makes for a more robust design at the head and foot end rather than simply down the sides. It means no loss of comfort across the entire mattress resulting in no roll-off and maximises the useable area of the entire sleep surface.

The mattress features Geltex, a unique patented gel infused foam in the pillowtop that gives great spinal support, pressure relief and breathability. Sealy Smart fibres with Tencel run through the entire mattress, which react to temperature and moisture to keep you cool and dry throughout the night. The mattress is also infused with Sealy Purotex, which is endorsed by the British Allergy Foundation, Allergy UK, as a natural solution to eliminating house dust mites and eliminating allergens from the sleeping environment. Add to all this the sumptuous pillowtop cushion with luxurious soft-knit fabric - you've got everything you need to get a perfect night's sleep.

Style and Practicality

If you’re looking for the full package, choose the divan bed base and mattress set, which provides the perfect foundation for your new mattress. The upholstered divan base is available in a range of four beautiful colours and textures, chosen to match or compliment any bedroom. The base is not only sturdy and stylish, but it's also practical.
