  • The Ashley Sierra Sleep Collection provides mattresses that cover a range of four different firmness options to cater to a wide variety of sleep styles. Here's a breakdown of each firmness level:
  • Ultra Plush: This firmness level is optimal for side and combination sleepers looking for shoulder and hip pressure relief. If you like superior cushioning and feeling more "in" your mattress than "on" it, Ultra Plush caters to this preference.
  • Plush: Slightly firmer than Ultra Plush, this firmness level gives slightly more support while still remaining ideal for side only or combination sleepers.
  • Luxury Firm: This is a medium firmness level ideal for all sleep styles, including back and stomach sleepers. Luxury firm provides the cushioning you crave with the support you need for healthy spine alignment. This is also the most popular comfort level of all Saatva mattresses.
  • Firm: Firm is best for back and stomach sleepers who still want a mattress that provides adequate give and responsiveness.

Construction & Design

The Ashley Sierra Sleep Collection makes three different types of mattresses: memory foam, hybrid, and innerspring mattresses.

  • Memory Foam: Ashley Sierra Sleep's Gruve memory foam mattresses provide body contouring comfort from soothing memory foam layers while keeping you supported with a thick layer of support foam. Charcoal and Green Tea infusions provide a refreshing sleep experience, while the Dual Ventilation technology and Micro Cool cover promote breathability and keep you cool. Standard memory foam models include comforting foam layers, a supportive core, and a stretch knit cover.
  • Hybrid: Ashley Sierra Sleep's hybrid models include a high density, super soft quilted top layer for deep pressure relief. Gel infused memory foam is designed specifically to fill out the hollow of your back for adequate lumbar support, while individually wrapped power coils respond to your unique shape to provide custom support. Two perimeter rows of pocketed coils provide ample edge support to keep the bed's surface stable.
  • Innerspring: Ashley Sierra Sleep's innerspring mattress features a 2" high density quilt foam top layer to ease pressure points and provide comfort. Its 13" gauge Bonnel coil unit responds uniformly to you body for even support and weight distribution. The high density support pad creates a stable base and makes this mattress more durable.

Support & Motion Isolation

The Ashley Sierra Sleep Collection generally performs well at motion isolation, but this depends heavily on which mattress you choose. The Gruve memory foam mattresses have no coils, so they produce little bounce to begin with. The Gruve's multiple memory foam layers are excellent at providing individual pressure relief and support without disturbing the rest of the mattress, so these mattresses are great for motion isolation.

The hybrid options are also great for motion isolation, and the memory foam layers absorb energy generated from movement, and wrapped coils respond individually without disrupting the rest of the mattress. The only mattress not recommended for motion isolation is the innerspring model, which generates more bounce due to its continuous innerspring system. Generally, the Ashley Sierra Sleep Collection is great for couples!

Just like motion isolation, the Ashley Sierra Sleep Collection performs differently at edge support depending on which mattress you choose. The hybrid mattresses use a perimeter of reinforced pocketed coils around the edge of the bed to prevent sagging and roll off, but neither the memory foam models nor the innerspring model features an edge support system. If you're looking for a mattress that's durable and stable, the Ashley Sierra Sleep hybrid mattresses are your best choice.
