Handmade in the UK, the Sealy ActivSleep Geltex Pocket 1400 Firm mattress helps provide a perfect night’s sleep. Featuring 1400 pocket springs, the mattress seamlessly moulds itself to your body throughout the night. Featuring a layer of Geltex – a material comprising of elastic gel and air-permeable foam – users will experience comfort like never before.
The Sealy ActivSleep Geltex Pocket 1400 Firm mattress is manufactured from the company’s state of the art ‘Smart Fibres’ that comply with numerous regulations and are Allergy UK approved. Extensive testing has gone into ensuring allergens in the bedroom are reduced and healthier sleep is achieved. The mattress is constructed using Adaptive materials that react to temperature and moisture levels for a cool night’s sleep, while the Unirail materials used to pocket the springs provide enhanced durability.
Pocket springs are springs mounted in their own seperate fabric pockets, meaning they work completely independently of one another and can provide your body with better pressure relieving support.
Geltex is a gel-infused foam which increases your comfort and body support. Geltex delivers triple benefits to offer the perfect sleep solution: incredible body support, ideal pressure relief and unrivalled breathability.
This mattress is approximately 26cm deep.
Good for people who change sleeping position.
The quilted cover is created by stitching the mattress cover and the fillings together, creating a patterned comfort quilt layer.
A single-sided mattress which does not need to be turned/flipped. One-sided mattresses should, however, be rotated head to toe regularly.
Individual personal sleeping zones mean that you won't be disturbed if your partner rolls or moves, as you won't feel their motion. There's also no tendency to roll towards the middle of the mattress.
Flag-stitched handles are attached to the sides of the mattress to assist in turning or rotating.
This mattress contains 1,400 individually pocketed springs (in a King Size).
Peace of mind and reassurance - the manufacturer of this item is an approved member of the National Bed Federation's Code of Practice.
