Lost cap for air mattress

I went to dirt cheap yesterday and purchased a Embark Air Mattress and once I got it home I discovered that the mattress didn't have a valve cap. I want to know if you could replace the cap without any cost? If you would like to send me one here is my address P.O. Box 282 Blue Mountain Miss 38610 Thanks for your help

You can find a pair of Boston valve caps by Kwik-Tek on Amazon for $5. I don't know for sure for you, but I've never met a boston valve that these don't fit.

I need to know how to order a cap for my queen size mattress

Some pumps come with a deflate setting so make sure to check that first. If not, you need to unscrew the cap off the valve and listen to hear that air is escaping. Then remove your shoes and walk up and down the surface of the mattress. Once you have done this a few times, you will be able to roll up the mattress from the end opposite the valve.

I was confused by this too. Here's the trick:

When you inflate the mattress, you unscrew the square-shaped plastic cap, like this:






But this is *not* the cap you unscrew to deflate it!

To deflate it, you have to unscrew the plastic at the *round* part that's beneath the square cape -- i.e. the part of the plastic that's affixed directly to the mattress. When you unscrew the round part, the entire plastic apparatus detaches from the mattress, leaving a big open round hole where the air rushes out.

It looks like this:

See the instructions near the bottom of this web page: (picture at the top of pasted instuctions on th link)

1. IMPORTANT! - Unplug waterbed heater for safety
2. Remove cap and seal and put aside in safe place.
3. Remove any excess air from mattress - slide forearm or broom handle from the head of the bed toward the fill hole to move air pocket
4. Attach the heavy duty hose to the hose valve coupling, connect to the waterbed mattress and other end to the pump intake side. Be sure to include O-rings. Gently push the coupling deep into the mattress.
5. Attach garden hose to the discharge side of the pump, this hose goes to a tub, or a deep sink.
6. Plug in the pump. When it starts it should have a low whirring sound, not a high whiny one. If water is not pumping immediately unplug the motor and check hose connections for tightness, verify there is no air in the mattress.
7. As the pump removes the water, be sure the hose valve coupling at the mattress is pushed down in the mattress to maintain suction. Heavy phone books or other like items will help maintain proper position deep in the mattress.
8. Keep pumping the water out and continuing to maintain the hose valve coupling position low in the mattress so it can keep pumping.
9. Do not leave the pump or the area until finished. A dry pump can burn up.
10. When the mattress is part way empty, you can place pillows under it at the head to help the water run downhill towards the hose valve coupling.
11. Continue pumping until water flow stops or pump changes sound. The more water you get out, the easier your mattress will be to handle.
12. If you are satisfied you have got as much water out as you can, remove the hose valve coupling and quickly replace the mattress seal and screw the cap on.
13. If the mattress is to be stored for a period of time, pour in a large bottle of waterbed conditioner into the mattress before you cap and seal the mattress.
14. We recommend rolling up the mattress from the head to the foot and carefully sliding one end into a wardrobe box. Another wardrobe box can be worked over the top of the mattress. Work one box into the other and seal both ends and tape the boxes together in the middle. You can now safely move the mattress.
15. If you don't get enough water out, the fiber layers can easily slide out of position during moving and you may not be able to get them back into position when you fill the bed.
