Every pillowtop will always get indentations, usually very quickly. There's nothing you can do about that and no toppers will help.
You can, however, cut the pillowtop off and create your own top layer or layers to suit you. There used to be a great many posts about this subject, with illustrations. I could find only the following, but if you Google it you're sure to find more info and instructions:
I needed a new mattress about 6 years ago to replace a 20-year old one. I found mattress shopping had become very confusing. I tried a soft one, and a very expensive Stearns&Foster pillowtop. Big mistake. NEVER get a pillowtop. No matter how expensive the mattress, the foam on top is cheap and will compress and form indentations within weeks. I too have back problems that send me to a physio every so often and was desperate for advice, which I got on this forum
That excellent advice was to buy a firm, regular mattress and then customize it and soften it with toppers - fiberfill, latex, or memory foam. I got a Kingsdown Duet mattress (I don't think the brand matters all that much, just don't get the cheapest) for about 800$ and it's firm, so firm I cannot sleep on it without toppers. I experimented using toppers and finally found what is perfect for my back by using two fiber filled toppers and a piece of foam just large enough to lay under my back. It took a bit of fiddling and shifting things around, but it was worth the bother. My bed is heavenly!
Six years later, the mattress is as firm and level as the day I got it - not a sag or indentation - and I'm still using the same toppers which I rotate. Many people have success with latex or memory foam toppers. I never tried them as I prefer to buy much cheaper ones so I can change them when desired without breaking the bank.
I hope this helps!
