This would be ok for use every once in awhile. I ordered my son the 8" and the 4.5" for myself. You can definitely tell the difference between the two and I had to put a lot of extra padding on the 4.5" for comfort because my back was hurting every morning. My son slept over somewhere else for a few nights and I slept on his 8" and slept great and woke up with no back pain. I would recommend going with the thicker mattress! Also, I noticed others commented on an odd odor which we did not notice at all with either mattress.
