Why we love this

The Tru-Cool cover on this luxurious mattress controls moisture and provides a silky smooth feel while the Avena foam alleviates pressure points.

About this item

  • 15.75" Select Firm Mattress with Avena Foam offers superior back support
  • Tru-Cool cover provides moisture management and a silky finish
  • Includes 9" boxspring

The 15.75" Select Firm Mattress by Spring Air offers incredible comfort and support. The Quantum Edge full surface adjustable pocket spring support system is designed for less edge roll off flexibility. The Avena Foam offers more responsive support than traditional memory foam while self-adjusting to key pressure areas. 1,344 microcoils are added to provide the right amount of support where you need it most. A luxurious Tru-Cool cover provides moisture management and a silky finish that is comfortable to even the most sensitive skin.


Quality You Can TrustEnjoy the luxury you deserve at a value that will let you sleep well. This mattress was designed to provide excellent support with managing back issues, limiting motion transfer and maintaining the ideal temperature. This quality and luxurious mattress is backed by a 10-year limited warranty.



Delivery, Set-up and Mattress Haul-away Spring Air’s White Glove Delivery+ Service* includes in-home delivery, up to two flights of stairs. The delivery agent will remove the mattress from packaging and set-up basic bed frames (if no tools are required). The member may ask the delivery agent to move a used mattress to another room at the location or haul-away the old mattress from the premises. Estimated delivery time is 10 to 12 business days for standard zones; remote zones may take longer. The delivery agent will call the member to set up an appointment.
