Very comfortable mattress, I have been unable to get a good sleep, after using this mattress, I feel more comfortable, I also fell asleep more easily, also not easy back pain. I can't leave this mattress now, it brings me too many unexpected benefits, soft and comfortable, it also looks very beautiful and generous, I just met some difficulties in the handling, it will be heavier, there is no problem with the other, I think their choice is correct, I love this mattress!
