There are 3 valve positions:
Open – No yellow or stopper flaps engaged, nothing in the hole of the SIM – you can see the white foam inside the SIM
Yellow Flap Engaged – used for manual deflation, the yellow flap is a one-way valve that allows air out of the SIM but does not allow air to re-enter the SIM
Closed – Engage both Yellow and “stopper” flaps after SIM is inflated and after deflation.
The SIM will self-inflate with 1 valve open (no flaps used, nothing inside the hole in the SIM) and 3 valves closed, or You can open all 4 valves.
either way, SIM will inflate to 85% or so in 2-3 minutes…this will be a comfortable firmness for most people to sleep.
Close yellow and stopper flaps after inflation.
Additional Inflation with included Air Pump
For those who want a very firm mattress…
With 3 valves closed, open one valve at the wide side of the SIM. Add air for 10-20 seconds.
Quickly close two flaps after filling SIM with additional air.
Deflation without rolling up the SIM for Transport in the Main Rear Trunk.
The least effort Requied.
With 3 valves closed, and one valve open (no flaps engaged) use the air pump (Use deflate side of pump). Run the air pump on the wide side of the SIM for 6 minutes Wet your pinky finger and hold it where the air flowing out of the SIM to know that air is still moving out of the SIM. Close valve quickly after deflation. Then fold the SIM in half lengthwise and attach the included straps. Result is a long 74×20 inch size which can be layed flat or put on edge to fit with the center seat folded down.
Deflation and Rolling-up SIM for Transport in the Main Rear Trunk.
With 3 valves closed, and one valve open (no flaps engaged) use the air pump (Use deflate side of pump). Run the air pump on the wide side of the SIM for 6 minutes Wet your pinky finger and hold it where the air flowing out of the SIM to know that air is still moving out of the SIM. Close valve quickly after deflation. The more air that is removed, the easier it will be to roll up the SIM. Leave the SIM flat on the floor and roll up from wide end to narrow end of the SIM so that valves are not covered by rolling it. Use Air pump again after rolling to remove any remaining air if necessary.. Close valves. Secure with 2 straps. This results in a 43×15 inch rolled up SIM, for transport inside the main trunk space.
Deflation and Rolling Up SIM for transport inside the Sub-Trunk.
The Not So Easy Way.
With 3 valves closed, and one valve open (no flaps engaged), use the air pump with the long nozzle attached to the “Deflate” side of the pump. Run the air pump on the wide side of the SIM for approximately 6 minutes. Close yellow valve quickly after deflation. Set all valves with the yellow deflate only flap. Fold Sim in half lengthwise. Roll up the mattress from the wide end to the narrow end. This way valves are not covered from rolling up the SIM. Use your knees to maintain your progress. After rollin up the SIM, secure with straps, then lay on, sit on the SIM to remove any remaining air. You can use the air pump again for this purpose. Close valves. Tighten the straps to realize the smallest roll possible. Place SIM in bag and store in sub-trunk for transport. (Or inside Frunk for Model Y)
Storage at home:
It is recommended that the SIM be stored inflated with 4 valves open. You can store it under a bed, or stand it up in a closet or garage.
Regarding the straps that go around the deflated rolled up or folded SIM. Suggest engaging the connectors and making a large loop which you then can put around the SIM – then tighten the straps to secure.
Suggest opening or closing flaps one at a time, rather than closing both the yellow and the stopper flaps at the same time. .
