this mattress topper is AWESOME! i completely agree with the person who wrote the review saying that this replaced the need for a new mattress. i 've had this on my bed now for a week, and it feels completely like a brand new bed. the memory foam is thicker than i expected, which is good because the feather part is thinner than i thought it would be - it's basically like a fitted sheet that goes over the memory foam, but that's fine with me! the day after i got this and put it on my bed (only took about 2 hours to completely take the shape) i came down with the flu and was in bed for 4 days. let me tell you - this item is worth every penny!
