My daughter was sleeping on a cheap memory-foam mattress on an otherwise great bed from Ikea, and she complained nonstop that it was uncomfortable; I also wondered if it was exacerbating her allergies. I knew I had to find a good compromise, in order to keep peace in the family, as my husband was in no mood to ditch the memory-foam. This mattress topper fit the bill, and I'm so pleased with it. Thick and plush, it transformed the uncomfortable mattress into a super-comfy sleeping experience. It has a good, clean wool scent, instead of the noxious chemical smell of the memory-foam. My daughter's asthma cough has abated and her complaints have stopped. I'm pleased that I could find a good organic option on Amazon, and the seller provided helpful customer service.
