Our son used this from ages 2 to 5 when we traveled and went camping. We also got it to help him transition from sleeping in a crib in daycare to sleeping on a cot. He was very comfortable and the cot is very easy to use, carry, and pack up. If you've ever assembled and disassembled a Pack-N-Play, this is 100x easier. There are no metal bars that press into the child's back. The canvas bed is held down with six plastic screw caps. One of ours broke and we were not able to order a replacement from the company. We fixed it by stopping at Ace Hardware and picking up a large screw and a large washer. I bought a few extra in case the other plastic caps broke, but we only ever had the one break. It was incredibly useful to have. Wish they made a slightly longer version as our son is now too tall for it and we'll need to get him a bigger cot for camping.
Found this product great for travelling. The bag is so big it fits everything in there. Also great for around the house when they are new home and you want to keep an eye on them, let them sleep in the lounge while you have a rest or in your room.. Although my little one has since grown out of we still use the bag for travel its great to fit everything she needs!
