I really like this. It folds up so small and is just what we needed. Since we have two kids under two, one needed a travel cot and we didn't want to need a second one! Our baby slept very well in this. It blocks out a lot of visual stimulation, which has really helped her since she's a bit sensitive. When we got home from holiday, I put it in her cot at home so she could carry on getting that benefit from it. The mattress is a bit thin, but babies' mattresses are quite firm anyway. Just put a blanket underneath the bed itself if you're concerned about a cold floor. A pillowcase works great as a sheet for the mattress, no need to invest in in special sheets!
