I really like this playpen. It's nice to look at at, easy to erect and not so huge it takes over your whole room. When folded it is compact and easy to transport.
But it is sold as a playpen and travel cot with "mattress" included. I'm not sure about that. The mattress is thin and doesn't seem particularly comfortable. It's also covered with a plasticky tent like material you would want to put a sheet over. But you can't do this safely because of the way the mattress attaches to the base - you can't tuck it in properly. I did the best I could and then watched as my baby wriggled around in his sleep and eventually got the sheet wrapped around his face. Not good. I've now bought a made to measure mattress with removable cover (a very reasonable £26.99 SUZY microfibre foam mattress made to measure on amazon) to make this travel cot into something we can actually use safely. I emailed Hauck about the problem with not supplying sheets which fit their product properly, highlighting the potential safety issue of people trying to use unfitted sheets. They weren't interested.
