This is a big heavy piece of furniture, but It does exactly what it needs to and it is on wheels!!  You need two people to open it up because it is so heavy, but the process is relatively easy.  My grandmother stayed with us for a week and slept on it.  She didn't have any complaints and said it was comfortable, but that the mattress was on the firm side.  I was actually happy to hear that because I was worried the mattress was going to be thin and flimsy. It was a really expensive item and I hope it lasts for a long time, but I think it will be great to have a queen sized bed available for any guests, but can also use the room as an office or nursery when guests are not here!
