I bought it because the mattress was too high to put on the bed frame! I wanted to buy 15cm, but they only had S. I thought it would be hard on my back if I put it on top of the 5cm topper I was using, so I put it on top of the 15cm topper and it was just the right height and soft! I think it would have been nice if there was also SS for the 15cm mattress.
