I was very disappointed about this mattress that is vacuum packed. Is not a firm mattress at all. You can see the coils on the back and sides of the mattress and feel them. The whole mattress would move if you seat at the edges of the bed. Is not firm at all. The quality of this mattress is really bad. I totally do not recommend this mattress at all. Is really a bad mattress. Don't buy it. Go to a local mattress store. Instead of buying a mattress online. When the mattress is vacuum packed for shipping.
