A convoluted foam topper pad provides a comfort layer, the Whisperflo 4200 air control system delivers individual adjustability for each side of the mattress, and a foam underpad ensures proper support. The oc400 delivers the essentials of comfort, posturization and support for great sleep.


Dual Adjustability

You prefer firm while your sleep partner prefers soft. There’s no need to compromise. Each of you can adjust your side of the bed for a perfect individual fit. Adjustment is easy—just the touch of a button. Best of all, your Comfortaire can be adjusted to always fit perfectly, even if your sleep needs change.

Interchangeable Components

Unlike traditional innerspring mattresses, which sag over time until they are discarded, Comfortaire mattresses feature modular construction that allows components like foam toppers to be changed out as they age. Components can also updated to keep your Comfortaire fresh like new.

Original Air Technology

The original air bed® technology that we invented in 1981, and have steadily improved over the years, still delivers the air supported sleep promise of comfort and individual adjustability. One thing hasn’t changed. Our quality is still unsurpassed.

Whisperflo™ 4200

Our Comfort Control™ air system allows you to adjust your side of the mattress to your individual comfort setting™ while preserving the comfort setting of your sleep partner. With 100 Digital Comfort Settings™, One Touch Memory and Instant Fill, you are in total control of your individual sleep needs.

Customer Reviews

  • Amazing bed
    Review by Robin (on 11/26/13)
    Meets Expectations
    We tried a bunch of considerably more expensive beds from competitors (both air and memory foam type beds) before finally returning to this bed in a king- we bought the comfortaire OC base model in a queen when we got married. This bed is the greatest...we got gel memory foam topper and these two are a heavenly combination. Excellent price for an excellent need to look elsewhere IMO.
  • No sagging

    Our OC400 is wonderful and doesn't sag at all so far. 10 inches is a good thickness I think.
  • Great

    I have back problems that make sleeping a nightmare and hate sunken beds so I decided to opt for an adjustable bed. So far, this bed has lived up to expectations, I like the adjustable air chamber and foam, I can change the setting based on how sore I feel. Supports very nicely. Trust me, the investment is worth it!!! Helps me function so much better during the day now.
  • Lot of bed for your buck
