Unfortunately, it is still very soft, my son is 6 years and a lightweight and decreases quite a lot, but sleeps well. Up to 45 kg - I would find it too difficult. In addition, it has no proper lateral stability, ie they swell practically laterally beyond the edge of the bed. It is positive that she no longer smelled after 3 days and the zipper for washing can be wide open super. The delivery was fast and without any problems, thank you.
