The Maxi Deluxe Premium Pocket Sprung Single UK Mattress has been specially designed to be 16cm in depth and is suitable for all types of single bed frames. Pocket sprung mattresses enable greater support and comfort as each individual spring is encased in its own fabric 'pocket'. These separate pocket springs allow more movement which in turn allows greater support for the body. Our Maxi mattress range comes with a 1 year manufacturers warranty with a 24-48 hour delivery currently available with every purchase (excl remote areas).
