Introducing the latest in modern hybrid mattress design: combing the best-selling features of cooling gel-infused memory foam and gentle comfort foams with premium innersprings for back-loving support.
Beautiful, Modern Design
Featuring a white, four-way stretch knit top, complemented by deep gray side panels, for a luxurious sleep surface and clean, modern aesthetic.
Cooling Gel-Infused Memory Foam
Simply Modern Mattress uses only CertiPUR-US® certified non-toxic foams to help reduce VOCs and provide healthy indoor air quality.
Comfort Foam for Airflow and Gentle Support
A generous layer of comfort foam adds resilience, improves airflow and provides gentle support.
Body Contouring Back Support
Our premium Quantum® Edge support unit by Leggett & Platt® features up to 975 fabric-encased coils (in the King size) — responsibly made from upcycled steel — for pressure-point relief and critical back support. This support unit reduces “roll-off” feelings and delivers a more consistent sleep surface all the way to the edge. Better still, the support unit is proven to be 26% more durable(1) than all-foam designs and helps prevent sleepers from rolling together.
The Simply Modern Mattress performs beautifully on any structurally supportive base, to include platform beds, bed frames with slats, foundations and even adjustable bed frames. In fact, it bends 24% easier than all-foam mattresses on an adjustable base.
Stretch Knit Polyester Cover
On the top panel, a quilted 4-way stretch knit cover (made from a blend of 60% polyester and 40% environmentally-friendly regenerated Tencel® fabric) allows you to reap all of the pressure-relieving benefits of the comfort layers below while easily allowing air to flow. This breathable layer is complemented by a slate gray embroidered border panel (made from a blend of 80% polyester and 20% poly-viscose) which features a mid-century modern design motif.
Gel Swirl Memory Foam
0.5 inch of CertiPUR-US® certified gel swirl memory foam relieves pressure points by distributing weight evenly across the mattress. Ideal for couples, it isolates motion so you won’t disturb your partner while you sleep. With the perfect amount of cradle and cushion, the gel memory foam creates a medium plush feel that’s great for partners with different sleep preferences.

Soft Comfort Foam
2.5 inches of soft CertiPUR-US® certified non-toxic comfort foam conforms to your body and provide deep pressure relief.
Comfort Foam Density: 1.5lb/ft3, ILD: 17
Quantum® Edge Premium Coils
The 8-inch tall innerspring is a Quantum® Edge unit made by Leggett & Platt in the United States States. It features fabric encased coil units, plus a reinforced edge and Caliber steel springs at the edge and foot. It provides a better edge than foam, reduces or eliminates that “roll-off” feeling, absorbs partner movement, and provides active response to your body’s movements. Unit coil counts range from 536 (Twin) to 975 (King) — all of which are individually wrapped and float independently.
1 inch of solid CertiPUR-US® certified support base foam absorbs your weight to dampen motion transfer and prevent noise.
