Product Description

The Sierra Sleep Limited-Edition 12 Inch Firm Mattress delivers unwavering support without sacrificing surface comfort. 

Its wrapped coil support system partners with high-density foams to hold your spine in a neutral, pressure-free posture, ideal for back and stomach positions. 

A breathable knit quilt cover crowns a stack of high-density luxury firm foam and zoned plush layers. Together, they dissipate heat and add just a whisper of cushioning before you meet the sturdy core. 

Because of this balanced build, many reviewers recognize it as an affordable 12-inch firm mattress that Ashley shoppers can trust for years. 

Edge-to-edge perimeter edge reinforcement keeps you stable when you sit or stretch near the sides, while coils tame partner motion so both of you enjoy motion isolation for undisturbed sleep. 

You can purchase it from us with confidence. This model carries a 10-year manufacturer warranty, ships free across the USA in an easy-to-assemble mattress-in-a-box, and arrives ready for adjustable base-compatible setups within 2-4 business days.
