It's a very well-constructed mattress, and you can see and feel the quality of materials used.At first, it seemed very comfortable and we was expecting a good nights sleep, but that was not the case, instead, it was kind of comfortable for short durations only, but then it became firm and almost like too much pressure was being put on joints etc.We ended up purchasing a hansleep mattress topper and the transformation was night and day.now its a remarkable nights sleep we get.
