This rollaway is quite comfortable. It accommodates my 6,2" 200 lb. son when he comes home for an overnight visit. Twin mattress pad and sheets fit perfectly. The only thing I don't like is that the metal bar that swings out to keep the bed together when closed, sticks out from the frame when open and is a potential hazard for hitting your leg on. I wish it fit flush on the frame when opened.
Although I have only used this bed twice since I purchased it, I can vouch for the fact that it is very comfortable for a rollaway. I selected this one because the dimensions are generous - the width makes it very easy to sleep on, and the mattress is surprisingly comfortable for a rollaway. Since we only have one guest room in our small beach home, it comes in handy when you have 3 guests. The only drawback is that, although it is supposed to easily fold back up, I've found I can't get the mattress to cooperate, so we have to store that separately. Very happy with the purchase!
