If purchasing a Replacement Air Chamber/Bladder the only measurement needed is the width (60″ Queen, 52″ Full or 36″ Twin) as the Air Chambers/Bladders are all the same length.
For example, the Queen Air Chamber is used in both the Queen and Queen XL Air Dream Mattress.
Please note: We do not recommend the Air Dream as an every-day mattress – only for occasional guest use. Also, we do not ship to Canada or other countries and cannot ship to US P.O. Boxes. Please call for shipping quotes to Alaska and Hawaii.
