The mattress is now are more than six months in use, and both sides were now used.
My son loves this mattress and no longer wants out of his bed.
The dimensions are great, we use an Ikea cot. In my opinion this is better than the mattress from Ikea, so I can advise everyone to buy this without hesitation!
Also is very important and especially good that you can wash the mattress cover and can refer back without any problems.
The shipping was fast and without any problems and the customer support is also properly (needed later the bill, within a day I was emailed this).
