I'm disabled and find that heavy mattresses make lifting the corners to change sheets and rotating the mattress as recommended really difficult for me.
My current mattress is an original Noa purchased in 2019, which is about 38kg. I also find it both too firm and with no edge support at the same time. It also retains body heat too much.
My wishlist is basically as follows:
* $1500 budget
* No firmer than medium
* No heavier than 35kg
* Does not sleep hot
* Some edge support
I've tried asking other places only to have people say that the weight of their mattress doesn't bother them, so I haven't been able to get anywhere.
Maybe you could reach out to mattress companies and ask them how much each mattress weighs?
A lot of them offer a trial period, so you could test out the mattress, if you dont like how it feels to sleep on, return it.
