After 3 days of waiting in a mis placement of my mattress it arrived in a box.  When I unpacked it, it sprang into shape and it's very well made.  I am extremely pleased although for me with a serious spinal condition I might by a memory topper as I have another bed with a gel and foam but this cost over £800 so I have given 4 stars for the problem with the delivery.  This is a fantastic value mattress and would recommend to buy.
