This is, as far as I’m concerned,one of the best mattresses I’ve had, just like the ones in quality that we used to be able to get. No rolling off if you turn over in the middle of the night! Not too firm, but even support all the way round so you don’t roll into the middle and have to struggle to get out of bed in the morning. Good strong handles/grips each side if you want to turn it, I haven’t needed to do this yet as the side I’m sleeping on is fine. The stitching all round the edge of the matress is still nice and firm so there is no loss of all round shape. I could not be more pleased with it, bit more expensive than some but worth every penny! P.S. my little dog loves it,sleeps peacefully all night and you can’t get a better compliment than that!
