Sealy Posturepedic support is built around alignment, not just softness
Sealy uses the support core and zoning to keep your midsection from sagging first, then tunes the upper comfort layers around that foundation.
As you move from basic Posturepedic models into Plus and Elite builds, the main changes are in cooling, edge support, and how much cushioning sits over the support unit.
Compared with the Sealy Posturepedic Memory Foam Firm 11", the Sealy Posturepedic Memory Foam Medium 12" is plusher and more pressure relieving than the Sealy Posturepedic Memory Foam Firm 11". That is the practical difference you feel in the showroom: the medium surface changes how deeply you settle in, while the underlying support build changes how easy it is to move and how steady the edge feels.
Shop all Sealy mattresses →Built for the way you actually sleep
Combination sleepers - The feel is balanced enough to work for shoppers who rotate between side and back sleeping instead of committing to one position.
Couples - This middle-of-the-line tuning is usually the easiest compromise when two sleepers do not want the same thing from the surface.
Hot sleepers - Cooling details in the cover and upper layers help, but if temperature is your top issue, the hybrid or step-up cooling model is usually the smarter comparison.
Shoppers cross-shopping the lineup - If the Sealy Posturepedic Memory Foam Medium 12" feels either too flat or too plush in person, the closest adjustment is usually the Sealy Posturepedic Memory Foam Firm 11".

Frequently asked questions
How firm is the Sealy Posturepedic Memory Foam Medium 12"?
We rate it 5 out of 10 (10 = firmest). In practical terms, that puts it in the medium part of the lineup. The right fit depends on your sleeping position, body type, and whether you like to sleep more on top of the mattress or more in it.
How is the Sealy Posturepedic Memory Foam Medium 12" different from the Sealy Posturepedic Memory Foam Firm 11"?
The Sealy Posturepedic Memory Foam Medium 12" and the Sealy Posturepedic Memory Foam Firm 11" are close enough in the lineup that most shoppers should compare them side by side. The biggest difference is feel: the Sealy Posturepedic Memory Foam Medium 12" lands on the medium side of the lineup, while the Sealy Posturepedic Memory Foam Firm 11" feels more firm.
Does it work with an adjustable base?
Yes, compatible with adjustable bases.
How fast can I get it delivered in Kentucky?
We deliver with our own team across Kentucky. Most orders arrive the next business day when the size is in stock. Pickup is available at our Lexington, Georgetown, Somerset, London, and Richmond locations.
What if I do not like it after a few nights?
You have 90 days to make sure the comfort is right. We usually recommend giving any new mattress at least 21 nights before making a comfort decision, because covers and foams need time to settle and your body needs time to adjust.
Can I try it before I buy?
Yes. We have these models represented across our Kentucky showrooms, so you can lie down on the feel before you buy. Walk in, take your time, and compare it against the nearby step-up and step-down models.
Try it in person at any Kentucky showroom
Walk into any Mattress Overstock location, lie down, and feel the difference yourself. No appointment, no pressure. Our team has over 100 years of combined mattress experience and we're here to help you find the right fit.
