No issues in January. My kids (8 and 6 at the time) slept there one night and then the older one refused to sleep there because the little one kept kicking her in her sleep. So we divided up and I slept on the sofa bed with the 6 year old for 5 nights and it was fine. I do like a firmer bed but, as a 41 year old average sized woman, I had no issues sleeping on it comfortably with a 6 year old next to me.
