Ashley Furniture has created its Sierra Sleep collection to compete with other industry giants and they’re comparable to beds that cost a lot more. The Sierra Sleep collection of mattresses are all ‘bed-in-a-box’ models. This just means they all get vacuum sealed and rolled into a small box for easier shipping to your home. It's one example of how they’re able to offer a lot of features at lower prices, Ashley is known for their great value in everything they make. In terms of key features, the innerspring mattresses in the Sierra Sleep collection use Power-Packed Wrapped Coils for a supportive feel. Combinations of foam such as high-density cushion firm foam, and copper-infused memory foam add plush comfort. Sierra Sleep’s hybrid mattresses combine generous amounts of gel memory foam and cushion firm foam with 8” power-packed wrapped coils. This combination of materials gives you the great support of innerspring coils, while still feeling soft and conforming with the foams on top.
