The Which? Best Buy Memory Superior Ortho Support 1500 mattress features 1500 pocket springs together with an additional 50mm layer of body moulding memory foam for that added support and comfort. The 1500 pocket spring system is ideal at providing individual support to the sleeper. The springs work independently and shape to the body contours. As they work independently each individual is supported dependent on their weight and therefore they each receive the correct support. The other benefit is that because the pocket springs are independent they help to prevent any roll together or any disturbance on one side of the bed affecting a person sharing the bed. The 50mm of memory foam moulds to the body shape of the person laying on it and gives the right support in all the right places of the body. The Memory Superior Ortho Support 1500 mattress is finished with a white stretch knit ticking, with three rows of side stitching. It is hand tufted with felt tufts to keep the mattress shape. The air vents ensure that the mattress breaths and maintains a fresh and dry sleeping environment. Handles are sewn onto the mattress sides to help when rotating the mattress top to toe. It must be noted that the mattress is non-turn. It has a firm feel and therefore will give that extra support. The Memory Superior Ortho Support 1500 mattress will continue to be a `best buy` and excellent value for money.
