Too thick for what? I think this is actually one of the thinner memory foam mattresses (6" is about as thin as I've seen). There is a 2-3 inch layer of memory foam on the top, the rest is a good quality high density regular old-fashioned foam. If you go thicker, in most instances you're not getting more memory foam, you're getting more of the foam under the memory foam (except for those pricey ones that try to razzle-dazzle you with all manner of proprietary foam layers). You really just have to decide a couple of things:1. Will your sheets fit an 8" mattress?2. Will the bed end up about the right height for sitting on (we all do... to take off shoes, etc etc)We bought the twin XL for my mothers hospital bed. Her old mattress was 6" and she was bottoming out on it. This one she says is unbelievably comfortable. She loves it!It's a good mattress... I don't think you'll be sorry. And the price is killer!

Q: To those who have owned this mattress for over a year, are there problems with "body impressions" or dents where one normally sleeps?

There are HORRIBLE problems with this mattress and Zinus Customer Support. I have owned this mattress for 4 years and it is no longer usable. I weigh around 160 lbs and the body impressions and sagging are horrible. Even though Zinus claims a 10 year warranty they will NOT honor it. Their customer service is terrible. Every time you provide them the information they requested they come back for more. Over and over they do this.

Q: How important is it to wait for 48 hours? Shortly after removing the plastic, it seems to be expanding nicely.

These mattresses typically take 48-72 hours to fully decompress, but they can take up to one week to fully decompress in some cases. You can sleep on the mattress during this time, sleeping on the mattress will not slow down the decompression process.

Q: can u sleep sleep on memory foam without the regular mattress under it

Yes, a memory foam mattress does not require a box spring or a mattress to support it. The mattress itself is fully sustainable on its own. For the first few months I had it on the floor and then bought a platform bed frame to put it on. It was a very cost effective move to purchase this mattress. Hopes this helps :-)
