Phoenix – thanks to your advice here, and on the parallel thread about local dealers in Burlington VT I was also involved in, we decided to order a mattress from Arizona Premium Mattress ( www.Mattresses.Net ) . Thanks to you getting the specs of the Nature’s Rest mattress we liked, we worked with Greg in Arizona to get the perfect bed for us. We’re actually upgrading from a 2" comfort layer to 3" for a relatively small upcharge. We’ve heard great things on your mattress forum as well as a personal recommendation for mattresses.net, so we have our fingers crossed! We’ll post back here when we get it in about 3 1/2 weeks. Thanks again for your help!
