Gilson spring mattress offers emerald series mattress [pocket spring mattresses]. This consists of a grid of springs, each in their own fabric pocket. Because they`re not wired together, each spring is able to work more or less independently; the weight on one spring doesn`t affect those surrounding it, hence when person next to you wakes up in the middle of the night the spring tension does not affect your sleep. Also a pocket-spring mattress is considered the most comfortable type of inner-spring mattress.
