Here is my review, a complaint rather. We have recently bought two Englander mattresses with boxsprings (innerspring with a memory foam layer). My wife said the mattress was retaining body heat. True, even I noticed it in my mattress. After a week, she could not longer sleep in her mattress and exchanged it for a different brand. I managed to use mine for a whole month because the store required that the mattress be used for at least 30 days. Another thing was that it was very hard when I slept on my side, sometimes my arm goes numb and often I wake up with pains in the back and shoulders. Finally, I followed my wife's strategy and got myself another brand in exchange. Since then things have improved a lot. I would not recommend this mattress to anyone.
