I recently bought a 1000 pocket springs one. They do not turn over. I had the worst non night sleep ever...Looked for another, but could not find what I needed. This one came up, it had many good reviews, and I thought, at the price I try it. It arrived rolled up in a box. When pulled out, it looked good....This one also does not have to be turned. It is memory foam, different layers, and the ordinary springs. It is so far very good and I sleep very well. It cost £45.......I can have one new every Christmas !!!!!
Look up on Amazon. I believe it is "Starlight" but not sure. Made in UK. gmx
