I don't know, but my mom had RA and she slept in the Lazy Boy living room furniture every night

Sorry, I don't think you will find anything comfortable. I've tried. Must keep moving, turning, lying, standing, sitting (from side to side). I agree, No fun.

I find the lean back into a relaxed the worse my hip and back pain are - hope you find something that suits, we are all so different☺️

I bought a memory foam mattress which makes sleeping a lot easier.

That is what I was thinking I had a lay z boy yr's ago. and I remember it being so comfortable. thanks
