Have had this mattress for about 3 weeks now and am really pleased with our purchase.  We had our old mattress for quite a long time and had both started suffering with bad backs.  Was worried about not testing this first, but having read other reviews we thought we would take the chance and am so pleased we did.  It’s very comfortable and the topper attached to mattress makes it feel very luxurious every time I go to bed and back pains have eased. Great price and great delivery.
