Thanks so much Mike the underlay arrived today Wednesday, and it looks as good as the biomag I already have, at a fraction of the price Thanks again C Butland Already we are noticing a difference in our sleeping patterns and at a fraction of the cost of similar products on the market! Thank you Megan Bramao We are really pleased with the underlay. I slept so heavily last night that I didn't even notice my 2 year old getting into bed with me. My husband says he is also getting a great night sleep. Vicki Canestri
