I currently sleep on a sofa pullout.

It's probably more comfortable than my queen size sagging mattress.

To avoid the Indentation, I sleep on the edge which Isn't Ideal- particularly for my height at 198 cm.

That sounds less than ideal. I dread to imagine what that does for your back and sleep.

I'd have to google that height in feet and inches, but I assume that is rather tall!
