How to Inflate a Self Inflating Mattress

The clue is in the name right? A self inflating mattress should inflate itself, but each style is different and each valve works slightly differently. See some handy tips below, to ensure you inflate your mat correctly. If your self inflating mattress is brand new, the first time you use it, it will not fully inflate by itself. This is because it has been packed and folded for such a long time, the best thing to do here, is let the mattress inflate, and then top it up manually using your mouth to blow air into the valve. Once the foam inside the mattress settles, you will find it will inflate itself quicker and easier.

A Regular Self Inflating Mattress (Brass Valve)

Does your mattress have one of the above valves, if so follow this brief guide to inflation:

  1. Unroll your mattress, and be sure to keep the bag and straps safe.
  2. Open the brass valve by unscrewing it.
  3. You should hear air rushing into the mattress.
  4. Leave mattress for 5 minutes.
  5. Top up the mattress using your mouth to blow air into the valve, to reach the desired pressure.

Does your mattress have the APC valve as shown in the image above.

  1. Unroll mattress
  2. Secure toggle from deflate to half way between deflate and inflate - this fully opens the valve.
  3. Leave for 5 minutes or so to allow air to enter the mattress
  4. Turn the green clip to Airtight - this closes the valve to stop air coming out, but you can then use your mouth to blow more air into the mattress.
  5. See video below for more information.

Frequently asked questions:

  1. Can I use a pump to inflate my SIM?

No, you cannot use a pump to inflate the mattress - the valve will suck air into the mattress, you should never attempt to use an airbed or tent pump to inflate the mattress.

  1. My mattress never reaches the full depth without me topping it up manually, is it faulty?

Each mattress is different, the self inflating mat design with the brass valve, will never reach the full 100% capacity of air inside, and you usually need to manually top it up. The more modern mattresses are far better at getting the air into the mattress, and you may only need to firm the mattress up manually if you want the mattress to be more solid.
