What can I say? It clamps the first few times all a little until you get a feel for the bed. But if we have the set up and removed a couple of times, you can really build up within 30 seconds all or completely cut off. It is then also stable. Here one must not be afraid that the child breaks out and the bed gets to collapse.
The mattress on the floor is fine for 1-2 nights, as a permanent substitute for a cot, but I would recommend here to get an extra mattress. That's just a little too hard and uncomfortable in the long run.
# Positive
+ Easy assembly
+ Reasonable price
# Negative
- A little high travel weight
Conclusion #
Have the travel cot bought, used and keep it in the future. Stowed in the supplied bag that's really unbeatable on the bulkiness about manageable and for this price. Clear recommendation from my side.
