Individual Barrel Shape Pocketed Coil is designed in a way where routes barrel-shaped springs are pocketed into individual fabric pockets. This significantly reduces motion transfer between you and your sleeping partner.
This is the most advanced and sophisticated off-set coil that is made with a 2.2mm diameter hard drawn, high carbon steel wire. Each spring unit is unknotted at the top and bottom ending, that flexes independently for maximum sensitivity to body contours.
This chiropractic coil is a classic and probably is the most well-known spring coil system, currently widely used in the entry-level spring mattress. It has an hourglass shape, the thinner middle part compresses with soft pressure while the rest of the spring provides deep down support.
