This listing is for ONE (1) Air Chamber, one side only. E- King or Eastern King. This was originally from a sleep number 5000 model.

Please see the quick connect plug to make sure it fits your pump.

Air chamber was inflated to 90 and maintained pressure for 24+ hours and it was still at 90. My remote was not working great but I was able to read enough to know it was at 90.
