My mattress did arrive damaged but customer service was extremely helpful to solve this issue and I did receive new mattress to substitute damaged one in few days. The mattress is for "Stompa" bunk bed European size (200 cm long). It fitted perfectly. Good height of the mattress for the top bunk bed as well. My daughter is 6 yo. Before she had foam only mattress and it was too firm for her and she is much happier with new one. It's medium feel, she says it's very comfortable and she does sleep well all night long. Very happy customers!
