I can't speak to the Zinus Topper , but I can relate to you my experience buying their mattress.
This week we have now returned to Amazon two Zinus 8" Memory Foam Mattresses .
The first mattress only expanded to 5" on one half and the other end expanded to 4" . Let it expand for 7 days before we gave up.
Amazon replaced with a second mattress . This one only expanded to 6" after 5 days .
The thing they had in common was a manufacture date of 2019 !
The industry recommends up to 90 days in the compressed condition . Otherwise the foam may be damaged and not return to original thickness .
I mentioned this to Amazon on the first return . Apparently they didn't follow up with their vendor .
We have requested a refund .
Hope you have better luck .
