The Katherine Latex Firm is a handcrafted innerspring mattress built for people who want a hard, supportive bed. Four inches of firm organic latex sit over a 7-zone pocketed coil system with firmer coils at the perimeter and the center third, so the edge holds up and the lower back gets extra push. The organic cotton cover and wool fire barrier keep it free of chemical flame retardants, and the button-tufted build is meant to resist body impressions. It is the firmest model in the Katherine Latex line and is not made two-sided, so it cannot be flipped.

The Katherine Latex Firm is a handcrafted mattress with a firm layer of organic latex over a firm pocketed coil spring system. It is the firmest of the Katherine Latex mattresses. It is not available as a two-sided mattress.
The comfort layers are four inches of 80 density organic latex, organic cotton batting above the latex, and an organic cotton quilted cover. All organic wool serves as the fire barrier underneath the cover. A button-tufted design joins the layers.
The coil system has up to 1462 pocketed coils in 7 zones. Coils at the perimeter have border firming rods for a firmer seating edge. Heavier-gauge coils through the center third add lumbar support. The mattress is built to keep the body aligned, relieve pressure points, sleep cooler and eliminate motion transfer. Its build style is meant to prevent body impressions. It is an ultra-firm option and is not suited for most sleepers.
