Our Comfort 1000 mattress is great value for anyone who is looking for an inexpensive, regular comfort, sprung mattress which has a slight bounce from the springs, along with great comfort from the foam layers. There are multiple layers to this mattress, which work in conjunction with one another, to help the user have the most comfortable and healthy night sleep. This mattress is designed using individually wrapped springs which provide support and bounce that materials, such as memory foam, cannot do alone. Each individually wrapped spring react independently from one another. This allows for two people to sleep together without affecting one another when moving. The gel memory foam and comfort foam layers provide further comfort and support. They are placed on top of the springs so you will not feel them when laying upon the mattress. Vacuum packed and rolled for easy delivery and transportation. Please note: once unrolled the mattress requires up to 72 hours to fully expand and reform to its original shape. This mattress is available in multiple sizes including: 3FT single, 4FT Small Double, 4FT6 Double and 5FT King. The depth of this mattress is 20-22cm
