My Take on The Ashley Sierra Sleep Hybrid 1400 Ultra Plush Mattress

by Jed Harrington

With a soft comfort scale rating, high end comfort materials, and a quality coil system, the Ashley Sierra Sleep Hybrid 1400 Ultra Plush has everything you need to enjoy comfortable sleep.

Soft and Supportive

If you enjoy sleeping on your side, or want a mattress that really conforms to your body, the 1400 is a great way to go. With a comfort scale rating of 8 out of 10 (10 being the softest) this mattress is highly adaptive and provides an enveloping level of comfort.

Comforming and Solid Support

The 8 inch power packed coil system provides solid support to the lower back with less motion transfer for undisturbed sleep.

Smooth Top Quilt Design

The Smooth Top Quilt puts almost no barrier between your body and the comfort layers, which allows them to fully conform to your body with zero inconsistency.

HD Gel Memory Foam

High Density Gel Memory Foam offers superior pressure relief to help reduce tossing and turning, outstanding durability, and helps reduce motion transfer for undisturbed sleep.

CertiPUR-US Certified

All Ashley Sleep foams are independently tested and certified to meet or exceed the higest quality standards.

Great For Hybrid Lovers

If you want the conforming comfort of memory foam with the support of an innerpsring, and enjoy a softer level of comfort, the Ashley Sierra Sleep Hybrid 1400 is a great choice!
