SofaBed Mattress is Horrible

Our sofa does not have a hide-a-bed but instead it all folds out and with the back cushions used as part of the matress, it makes a queen size bed. My son and daughter-in-law slept on it and stated the only problem was where the back cushions go makes a slight hump. They said although it was not terribly uncomfortable, they felt like they were sleeping on their head the first night. The second night, we folded up a blanket across where the head should be to elevate it slightly and I went to Walmart and purchased a 2" memory foam queen topper. They said it slept great that night. When packing up, I discovered that the memory foam would not fit in the storage under the couch easily because those darn things are contrary. We folded it over and the rolled it short end to short end. Then used a bungie cord around both ends to hold it in place...it now fits nicely in the storage under couch and is ready for the guest when needed. If you don't have storage under your couch with your hide-a-bed and if your couch won't fold up with the topper in place, perhaps you could store it under the master bed to keep it out of the way when not in use.
