12 Inch Ashley Hybrid King Adjustable Base and Mattress

$1,850.00 $2,405.00

The Hybrid 1200 king mattress and king mattress foundation set is simply a better way to get a great night’s sleep. The mattress gives the contouring support of a traditional coil mattress and the firmness of gel memory foam, providing restorative support for your lower back. The riser is an all-in-one support system that takes the place of an ordinary bed frame and box spring. And setup is as easy as 1-2-3. Step one: Follow the riser’s quick and easy \"no tools\" assembly instructions. Step two: Remove the mattress from the box and unroll. You’ll be amazed at how it fully expands within minutes. Step three: Enjoy a great night’s sleep.
