The Sierra Sleep Plush 3.0 from Ashley Furniture is built around a straightforward idea: genuine softness that still supports you through the night. The quilted top layer uses high-density foam for an immediate cushioned feel, while gel memory foam underneath cradles pressure points at the shoulders and hips without letting you sink too far. A high-density support foam base keeps the spine in line across all sleep positions.
Below all of that, a wrapped coil system handles motion isolation — each coil moves independently, so a restless partner or a pet shifting at 3 a.m. doesn't transfer across the bed. The reinforced edge construction extends that support to the perimeter, giving you usable sleep surface all the way to the border. The knit cover stretches in four directions for consistent contact with the body rather than bunching or pulling.
At 13.5 inches tall, it works with most standard and adjustable bases. The mattress ships compressed in a box and needs 48 hours to fully expand before use. Backed by a 10-year non-prorated warranty.
