325 lb male and a natural escape my green mattress

Hi,

Trusted members, I hope you can help me.

My wife is considering the natural escape from my green mattress and I am concerned how the mattress would hold up to my weight. I am big man (325 lbs) with shoulder and lower back pain. I am not sure if this mattress is right for us ( living in Canada) so not an option to go to the store and check it out.
My wife wants a green mattress, I don’t mind if it is or isn’t, as long as it gives me a good night’s sleep.

Alternatively she suggested happsy or naturepedic eos classic or pillowtop. Naturepedic version costs me more than 5000 bucks which imo is a lot.

Please. Any suggestions, advice welcome !

Thanks !
