My daughter has been struggling with allergy induced asthma for some time now, and getting this mattress was a brilliant decision. In addition to the other measures we have taken to get her dust mite allergies under control, since the first night on this mattress, her congestion in the morning is literally GONE. No more sniffles when she wakes up, or coughing, puffy and watery eyes - this mattress is the best money we have spent on her. We shopped around all over the internet, as well as all our local furniture stores and we could not find another twin mattress even close to this price. I initially cringed at spending so much on a twin matress, but it is more than worth the money for the relief she has gotten! I would recommend also getting a latex pillow and allergy cover as well if you're buying this for that purpose. Overall a great experience and product from overstock.com!
