Duo Mattress FAQs

A Duo is our 2-piece mattress. The bottom piece is the Duo Support, a pocketed coil base you can flip for a slightly softer or slightly firmer feel. The top piece is a removable Duo Comfort layer, held in place by CLING™, our patented attachment method, with no zippers or straps. When the top wears out, you replace only the top.

On our Firmness Guide, the Duo Essential is the firmest at 7-9/10. The Duo Latex, Duo Memory and Duo Lift are 6-8/10, the Duo Latex Plus is 5-7/10, the Duo Performance is 4-6/10, and the Duo Memory Plus is the softest at 3-5/10. Firmness is subjective, so you can also flip the Duo Support for a slightly softer or firmer side.

Our Firmness Guide suggests the Duo Essential for back and stomach sleepers, and the Duo Latex for back, stomach and combination sleepers. Side sleepers who want shoulder and hip relief usually look at the Duo Memory Plus. The Duo Latex Plus offers a medium balance of comfort and support, and the Duo Performance is listed for most sleepers.

The Duo Lift is made without foam or latex. Its comfort comes from over 4,000 coils, New Zealand wool and organic cotton. The Duo Performance is the Duo we designed for active people and plus-size sleepers, with high-resilience Avena foam over Serene foam on the Duo Support.

Yes. Flip the Duo Support for its slightly softer or slightly firmer side. On the Duo Essential, Memory, Latex, Performance and Lift you also get one Comfort Exchange, so you can switch to a different Duo Comfort top. If you’re still not comfortable after about 30 nights, you can use it any time during the 100-night sleep trial.

Yes. Duo Comfort Tops are sold separately in all seven Duo feels and in Twin, Twin XL, Full, Queen, King and Cal-King, so you can refresh the comfort layer or change the feel and keep your Duo Support. The Duo Comfort Top has a 5-year warranty and the Duo Support has a 10-year warranty. A Comfort Top bought on its own is non-returnable.
