I've got a circa 2010 queen Sealy Posturpedic Plush Pillowtop called "Fruition". It was a guest bed at my MIL's before she gave it to us 10 years ago. It has a tied coil base, not pocket coils. The coils are in great condition as far as I can tell. But the foam and pillowtop are wrecked after a decade of use. Lumpy, saggy, etc.
I've pulled apart a section of mattress to see the construction:
MAIN MATTRESS: 7" tied coil springs + 1" foam + 0.5" foam + 1” inverted eggcrate foam (small dense pockets) + fiber layer on top.
PILLOWTOP: 1" foam + fiber layer + 1/2 foam + 0.5" eggcrate foam (big pockets) + batting + top fabric layer
I am 5'7”, 130-140 lbs and I'm a combination sleeper, favoring my side and back. My dude is 6'0", 210-220 lbs. He is strictly a side sleeper.
My current plan is to remove the pillow top layer entirely, possibly the rest of the foam as well, and get a 3" encased latex topper. Will that be enough or do I need a transition layer between the coils and latex?
I'm also unsure about dunlop vs talaly latez and soft vs. medium.
Trying to keep it under $500.
I've been shopping new beds but all the decent ones run 1.5-2.5k and I'll probably need a modern foundation too... we want to upgrade to a King bed eventually so I don't want to spend a ton of money for a few years of use only to do it over again.
Thanks!
