Inside the product

Built around better response.

Tightcore Bounelle takes the proven bonnell core and increases its support density. Smaller-diameter springs allow more coils to be positioned across the unit, creating more support points and distributing weight more evenly. The tighter spring unit provides a firmer and more controlled response while keeping the strength and durability of a bonnell core. Available in customised wire diameters, spring heights and firmness levels, Tightcore Bounelle is designed for mattresses that need greater stability and firmer support.
