So I am almost 12 weeks post op and have lost 40 pounds so far. I have been waking up with a slightly stiff back the past few days and I’m wondering if the memory foam mattress that has a larger body impression is causing my back problems?? Has anyone else had similar issues??

I can tell you a large body impression can cause back problems. Our last few mattresses did not hold up to our weight. My husband is 6'10" and a big guy and when I was almost 400 pounds none of our mattresses lasted more than 2 years without getting large body impressions and we both had back pain.
We bought a Big Fig mattress a couple years ago. It's is made for bigger people and it's has been amazing. There are no body impressions even on my husband's side.
A good mattress definitely makes a difference!

We had a lot of issues with our mattresses over the years. Both of us were overweight which caused us to basically buy a new one every couple of years. The last one we bought, we spent a good amount of money on it. It's called posturepedic and its awesome.

We bought a sleep number in Feb 2020. The best bed I’ve ever owned. I’ve noticed I need a lower number as I lose weight.

Oh that's the one that hubby said we are getting next.

I also have a Sleep Number. I highly recommend.

Seriously recommend a split king with adjustable bases. We’ve been married for 16 years and sleeping in my “own” bed was a game changer. We sleep sooo much better. No issues on the marital activities

I own a purple mattress and bought it in August of 2016. Even at our heaviest weight we never had a body impression and the bed doesn't need to be rotated. We bought this bed due to my wife's back injury and this bed has significantly improved our sleep. Even after losing all of this weight we still find the bed just as comfortable as it was before!

I always wondered about the purple mattress.

Thank you everyone for your suggestions. I already have adjustable bases and thought memory foam was my only option to put on top. I will look into the other mattresses mentioned though because my husband agreed it’s time to invest in good mattresses.
