This is a 12-inch firm full-size innerspring mattress from Sealy, sold with a matching boxspring. It pairs Bonell coil springs with a memory foam layer on top, so you get a hard, stable feel with a thin cushion over the coils. It suits back and stomach sleepers and heavier adults who want a rigid surface, and it is a traditional alternative to all-foam beds that sink and run warm. Expect a bouncy, edge-stiff mattress that sleeps cooler than pure memory foam but offers less contouring and motion isolation than a hybrid or pocket-coil rival.

Owner feedback on firm Sealy innerspring mattresses with a boxspring tends to praise the rigid support and cool sleep, while criticising the hardness for side sleepers and the motion transfer between partners.
