My Take on The Ashley Sierra Sleep Palisades Firm Mattress

by Jed Harrington

As more and more manufacturers start to move to bed in a box, Ashley sets itself apart by being one of the first offer substantially higher quality mattresses at an affordable price. The Palisades Firm is a great example of this movement. It packs a ton of value into a very affordable price, resulting in proof that you don't have a spend a lot to get a great mattress.

Firm, Yet Forgiving

If you like a firm comfort, but don't like sleeping on a carpeted floor, the Palisades Firm is for you. With a comfort scale rating of 3 out of 10 (10 being the softest) it has a firm overall feel, without feeling hard.

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.

An Overall Solid Choice

Overall, if you like a firm feel, and want to keep your costs down, I highly recommend the Palisades Firm. Are there better mattresses that cost more? Sure, but this is one of the best values available anywhere in bedding and with Ashley working hard to sell more mattresses, it's a great time to take advantage of the value they're offering.
