Original Product Description:

This pocket-sprung mattress will allow you to enjoy your most restful and refreshing sleep. Because every spring is housed in its own chamber, they respond individually to the contours of your body for effortless comfort without sagging. You'll also find they reduce motion transfer, so you and your partner won't disturb each other as you adjust your position while you rest.
