Sierra Sleep 12 Inch Memory Foam Mattress – Double the Foam
Price range: $186.99 through $332.99
Twice the memory foam is the headline here – a full 2-inch contour layer, double what entry models carry, over a 10-inch firm support core. The result is a medium feel with real pressure relief: shoulders and hips settle in, the core holds the line, and the stretch knit cover keeps the surface breathing.
Twin and California King bookend the size options – one for the hardest-working beds in the house, one for the longest – and both are adjustable-base compatible.
Ocean City and Egg Harbor Township sleepers can press the difference between one inch of foam and two at The Mattress Store inside our Northfield showroom.
Questions & Answers
How does the 12-inch Memory Foam feel?
A true medium – the 2-inch contour layer gives real pressure relief while the 10-inch core keeps support steady.
What sizes and prices does it come in?
Twin $419.99, California King $749.99.
What does doubling the foam layer change?
Deeper contour at the pressure points – the difference between foam you notice and foam that just softens the quilt.
Does it work with an adjustable base?
Yes – the all-foam build flexes cleanly with head and foot elevation.
What warranty applies?
Sierra Sleep’s 10-year non-prorated warranty – ask our team for the details when you order.
Frequently Asked Questions
How do I know which firmness is right for me?
Side sleepers usually do best with soft to medium feels, back and stomach sleepers with medium-firm to firm. The surest way is the 7-minute Dream Catcher pressure-mapping test at our Northfield showroom – it shows your pressure points on screen instead of guessing.
Do I need a box spring or foundation with this mattress?
Most modern mattresses need a solid, flat support – a foundation, platform bed, or adjustable base rather than an old-style box spring. Check the product details or ask our team what pairs correctly with this model.
What sizes does this come in?
The size options on this page are the sizes we carry for this model – pick your size above. If you need a size you don’t see, ask our team about special ordering.
