Moving out and in search for a new mattress

I’m moving to Vancouver Canada in a few weeks do study university, it’s my first time having my own place and also my first time needing s new mattress.

I’ve had the mattress I use right now for 16 years, it is a selther ortoflex G5 and it has been amazing, I’ve never had any trouble with this mattress; now it’s time to change it but I don’t seem to find something that compares. I was looking to the Logan & Cove Choice mattress but reviews are harsh on it and I don’t fell convinced, same happened with the Ikea mattresses. I am 5’8/172 and around 60kg/132lbs, I am a side sleeper and I’m looking for a hybrid mattress.

Because I live outside of Canada as for now I cannot try most of the mattresses that y’all may recommend, but I’m up to throw myself with and unseen mattress if it looks like what I’m looking for: a medium firm mattress, hybrid, full size and below $1000.

If any extra information is needed please respond to this so we can talk.
