If you find yourself traveling in an Airstream RV, travel trailer, or van, but are struggling to sleep during your travels, then it may be time to consider a mattress upgrade. While Airstream travel trailers have become the icon for traveling comfortably, and in style, the mattresses that Airstreams come stocked with only bring comfort so far. With an outstanding selection of van and travel trailer configurations, there comes just as great a selection of sleep setups. We always suggest you measure the bed in your Airstream RV, travel trailer, or van because the mattress size really depends on the model and year of the Airstream itself. To simplify the mattress buying process for your Airstream, we have put together this easy-to-follow guide about all things RV mattress.

About Airstream Mattresses

Airstream has a long history, having produced its first model in 1936. With such a long history, it is no wonder that there are over 780 different floor plans. There were around 50 different Airstream models between 1999 and 2013 alone. Unfortunately, this makes finding the perfect replacement mattress for an Airstream RV, travel trailer, or van, a process. Newer Airstream beds typically fit one of eight custom RV mattress sizes, which makes it challenging to find the correct RV mattress size at a brick-and-mortar location. When it is time to replace the mattress in your Airstream, we recommend this simple approach - measure your current mattress and check out our selection at At SleepDog®, we offer multiple RV mattress size options that can be delivered right to your door. The two most common mattress sizes found in Airstreams are:

  • Twin XL (38” x 80”)
  • RV Queen (60” x 75”)

About the 2021 Airstream Flying Cloud

Airstream travel trailers are truly an icon when it comes to comfortable traveling. For 2021, Airstream decided to give its Flying Cloud travel trailer a stylish new interior design. The 2021 Airstream Flying Cloud features updated bedding, as well as new color schemes, modern kitchen fixtures, new cabinets, new upholstery options, and much more. This model is available in fourteen different layouts and floorplans, all of which can be configured with either a twin XL sleep setup (34” x 80”) or RV queen size (60” x 75”) bed.

OEM Airstream Mattresses vs. SleepDog® RV Mattresses

The OEM, factory-made mattresses that come with RVs are not always designed with comfort in mind. While the OEM mattress may work for the time being, after substantial use you might find that it is relatively uncomfortable and not designed to withstand daily wear. Aftermarket mattresses are designed with the intention of making life on the road a little cozier. All SleepDog® mattresses are designed in sizes and constructions perfectly suited for the smaller spaces you find in RVs, campers and sleeper cabins, while still providing substantial support for all sleep preferences. The memory foam in all of our mattresses is CertiPUR-US® certified, which means they are safe for you and your family. With free shipping, free returns, and a 10-year warranty we can guarantee better, safer sleep, hassle-free. If you have additional questions about what mattress best suits your Airstream RV, please contact our Customer Service team for assistance.
