Comfortaire beds are the best! We have purchased 5 of them over the past year and we love them. We buy ours online at
www.nationwidemattress.com and Richard takes great care of us. I'm just a customer, not a salesperson, but the Comfortaire beds are adjustable, comfortable, well-made and durable. We have the "dual-air control" on ours, but our kids and grandfather have the single air mattress beds. Just put the mattress on a box or foundation (not box springs) and you're all set. Very comfortable!
