Airsprung Viva Hybrid 1000 Pocket Mattress in Single, Small Double, Double, King and Super King Sizes Are all hybrid mattresses the same No, but typically they tend to combine two things: This model has been cleverly created using 1000 movement-reducing mini pocket springs - on top of the well-renowned Airsprung Supercoil open coil spring system. So that’s double springs in one mattress! Most comfortable, this Viva Hybrid 1000 Pocket is made by brand Airsprung. It’s available in all sizes from a Single, up to a glorious Super King size. Medium in feel, ultra-comfy as it should be and with a quilted finish, the quilted Belgian damask cover also uses Ultimate Freshness - a complete anti-dust mite, anti-bacterial and anti-microbial surface treatment for all round protective reassurance. The comfy white fibre fillings (made from 80% recycled plastic) are on top of the Reviver insulator layer (100% recycled) which give a reassuringly even feel; also meaning a breath of fresh air for the environment. Designed to be non turn, this means convenience and common sense, with all the layers arranged on the sleeping side for maximum comfort and durability. (Don’t forget to rotate occasionally to prolong its longevity). So are all hybrid mattresses the same Certainly not - with comfort and affordability in equal measure, this is proof you really don’t need to break the bank to be assured of deep, restful sleep - time after time.
