Expert Review by Jed
The Ashley Sierra Sleep Sierra Firm mattress is a good choice if you're looking to keep your cost as low as possible. This mattress doesn't contain any of the higher end features, like memory foam, found in other models, but for a temporary situation, it should work well. A 1 inch layer of high density comfort foam provides a firm overall feel, while the Bonnell Coil System provides support to the lower back. This mattress is designed to provide comfort for short durations, or sporadic use, and carries a 1 year warranty.
