This Bonnell spring mattress offers a pleasant feel and a comfortable sleeping experience. The fabric features a simple and clean look while being breathable, skin-friendly, and durable. The Bonnell spring system consists of interconnected hourglass-shaped steel coils that are firm and stable, providing excellent support and longevity.
