innerspring

An innerspring mattress with coils might have a more even construction because it’s protected on all sides and can be rotated and flipped.

High-density foam seat and back cushions are wrapped around innerspring coil core and then upholstered in a durable weave. $1,299.

Innerspring: A mattress with a supportive core of steel coils in either an interconnected unit or as individual coil “pockets,” surrounded by foam, gel or batting.

A high-quality latex mattress may last more than 20 years, and an innerspring core more than 10 years — but many one-sided mattresses today last only a few years, no matter what they’re made of.

We first tested what are known as hybrid mattresses—those with a mix of memory foam and innerspring coils—in the optimistic hope that we’d both be instantly pleased.
