Good mattress
This is a good mattress. It's good value for money, and although it doesn't feel particularly comfortable when you first lie on it (it feels kind-of dense), for the first time in many years I'm not getting back pain, or pressure point numbness. I'm sleeping without tossing and turning and waking. I tend to sleep quite hot, and I'm not detecting any heat from the foams, either.
The returns policy was the main reason for my trying a mail-order mattress, but from the first night it was great, so I do not imagine I'll be returning it.
Probably just as well, TNT sent it out (to a rural area) in a giant truck, which the driver wasn't game to drive up my driveway so I had to drive down to the road and load it into my car. As these are heavy mattresses that caused a few hassles for me, but I managed to get the box in and onto the bed.
I'd recommend people have a removalists trolley, as the box cannot handle being pulled up steps, the wooden insert with the handle comes out. But with a trolley, it's a lot easier.
