My Take on The Ashley Sierra Sleep Palisades Plush Mattress

by Jed Harrington

The Sierra Sleep Palisades Plush is an excellent overall mattress, especially at this price point. Due to efficiencies in automation and their desire to sell a huge amount of mattresses, Ashley is going after the big players in the industry by offering a tremendous value. The Palisades is a perfect example of this. It checks all the boxes for quality and has a solid coil system that performs well resulting in one of the best overall values on our site.

Goldilocks Comfort

The Palisades aims to please across all body types and sleeping preferences by offering a not too firm, not too soft combination of comfort and support. Back and stomach sleepers should do very well on this mattress, but side sleepers may want to look at the pillow top version to ensure even better pressure relief.

Individualized Support System

The power packed coil system uses individually wrapped coils that contour to your body's unique shape better than traditional tied units, while promoting proper spinal alignment for outstanding support. It's great for light sleepers because it reduces motion transfer when movement occurs, and it's adjustable base friendly!

Reinforced Center 3rd

A layer of premium gel memory foam provides extra support and durability to the center 3rd of the mattress where you need it most.

Zoned Comfort Foam

Zoned comfort materials conform to the unique shape of your body, ensuring proper softness and support where you need it.

CertiPUR-US Certified

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

A Fantastic Choice Overall

I'm hard pressed to find a better value than the Palisades Plush at this price point. It's elegant look, adaptive comfort level, and quality coil system make this an outstanding choice in the value category.
