My husband has Rheumatoid Arthritis & has trouble with his hips & knees that keep him up at night. A new mattress didn't help so I researched toppers & discovered a latex topper was what he needed. We'd tried memory foam (made him hurt worse) & other toppers without much luck. We've been sleeping on this topper for several weeks now & love it! He hasn't slept this well in years!!! I will probably order 2 more for my teenage children & recommend it to my friends & family.
