Our spring coils provide comprehensive, targeted support while you sleep.

There's a reason we've used coils in our mattresses since we first started making them in 1987 — they provide unparalleled support. Each coil is individually encased, with targeted zones that contour to your body.

ActivEdge Quantum Edge Coil Unit

These hybrid latex mattresses feature the Leggett and Platt ActivEdge Quantum Edge innerspring unit. The Quantum Edge coils provide a reinforced perimeter, made up of narrow-diameter Quantum® coils, which deliver a consistent sleep surface and reduce that roll-off the bed feeling.

Bolsa fabric encased coils provide an even surface that absorbs partner movement and prevents sleepers from rolling into each other. This system features pre-compressed coils that create a firm sleep surface, which makes the unit more responsive to body movements, and stress-relieved wire to hold shape and provide a durable and consistent sleep surface.

Our 8-inch ActivEdge Quantum® Edge coil unit from Leggett & Platt® features up to 975 individually pocketed coils made from upcycled U.S. steel, plus a reinforced perimeter.

Coil counts: Twin: 572, Twin XL: 681, Full: 727, Queen: 789, King: 975, Cal King: 958.

Gauge Count

The dark blue zones (in the above photo) have a 13.75-gauge and the light blue perimeter zones and white zones have a 16-gauge count. Lower gauge numbers indicate the steel is thicker. The edges use a thinner 16-gauge metal, but are coiled more tightly and have more coils per surface area that provides extra edge support.

Micro-Coil System

Our Oceano Mattress also features a row of 2.4"-thick micro-coils — a performance layer that eliminates the need for extra foam that delivers durable, responsive comfort. They add an extra level of comfort and durability and sag-resistance that outshines other comfort layer materials, like foam.

Quantum Edge Coil System


The hybrid version of our Cypress Mattress includes the Quantum® Edge innerspring unit, which features side rails made up of our narrow-diameter Quantum coils with Caliber steel. Quantum side rails deliver enhanced support at the edge of the bed and the Caliber head and foot coils offer a more supportive edge than foam encasement.

Coil counts: Twin: 536, TwinXL: 572, Full: 681, Queen: 789, King: 975, Cal King: 958.

Gauge Count

The Quantum coils on the perimeter are 16-gauge. They're turned tighter and have more coils for extra edge support. The Caliber steel springs at the head and foot are 13.75-gauge. The lower the number, the thicker the steel.
