My husband and I are both in our 80's. The box was dumped on our porch with no knock or ring. Managed to get it open and into house and after several attempts got it together. 
It was much larger than expected and very uncomfortable. Wanted to send it back but it said we had to rebox it in original material and there was no we could do that plus they would charge $100 return fee. As we are on fixed income, we couldn't afford to spend $100 on nothing so kept it. Not at all happy with it or our experience.
