Can you use it as a seat cushion too...Or wouldnt the valve hold the air?

You could use it as seat cushion, but eventually it will spring a leak, I've bought 5 different lumbar inflatables and they've only lasted between I week - 2 months. it's meant to support the weight of a persons lumbar back, for example, when they are reclining in chair, so it should be able to be sat on. Problem is leaking regardless how used.

It is not designed to be a seat cushion. It would be uncomfortable. The design is that it has only enough air in it to make it mold to your back. In fact if you over inflate it, it is not comfortable on your back. You could sit on a seat style cushion and use this for you back and it is very comfortable. I hope that is helpful.

I bought the cushion as a back pillow and it provided the best relief ever, however it did develop a leak after about 5-6 months and therefore I would hesitate to use it as a seat cushion unless you don't mind replacing it more often as needed. Again, it does give great relief.

Yes. If you prefer it firmer, you are able to add some air by blowing into the valve.

It is air filled and you can control how much air it has at any given time depending on your needs. It has a good pump and a valve to let air out. It is very well made and extremely comfortable cushion for an office chair, car seat or wheel chair. I use mine primarily in my car, sometimes to sit on and sometimes as a back cushion on long drives.

I really don't know, but I found out that it had way too much air in it and if you use the valve you can let some of it out. I felt like I was going to fall off of it. Don't do what I did before I knew about the valve and punch a hole in it to let the air out.

It will retain the air in a pool. Curious -- how would you use it in a pool? I would think you would float off it. Maybe use it with weights in a pool to hold you down?

if you lose air, it won't be significant. Most valves are in-line, not 90 degrees.The shock, or wheel really should be designed for in-line attachments - not the pump's fault.

I use mine for this, and it is great to be able to increase the firmness by just opening the valve. For me the valve is able to hold whatever pressure I set, and the self inflating feature is excellent. Mine is 2.5 years old, and I am very happy with it.

I agree with the other reviewer, just overfill a couple of pounds. Not much air should bleed out unless you have a faulty valve.

Mr. Rossen, the product actually belongs to my roommate. I supplied the furniture and it seems to fit the bill for durability. The air valve is internal I believe. I will pass this thread of conjecture to them for a more definitive answer.

Yes! My over 200 lb son has used it and once you adjust the air with the valve, it's very comfortable. :)

YES it would make a great stadium cushion. Just take care not to over inflate it and you should be fine. We have had ours for a few years now and it is still going strong. We have used it as a pillow, cushion, etc. camping with no leaks

They don't provide a valve and it would make it much easier if you could just pump it up. Blowing it up took so long that i eventually quit and tossed the wedge out when I got home. You would need a bicycle floor pump and a half hour to pump it up. Getting it flat after it is inflated is a challenge also.

I'm not sure. It could have been something my son did. But, I will say, it is definitely worth a try especially with Amazon's great return policies. We still use it, you just have to get used to how to play it with the valve.

The valve is the type that you need a bicycle pump. You cannot blow it up by mouth.

No. My friend has one that I have used. As Allan stated, you must push the lever for air to pass. The braided hose is too short. When airing up and the valve stem happens to be nearer to the dirt, you have to bend over until the tire is filled. From 15psi to 40, in the hot desert sun, it can be bleh. If it were longer, I would buy it. I'm looking for a better one.

I have had no problem with the valve. The stopper goes in gently, and it hold the air till I am ready to deflate. When flying, you are not supposed to inflate it until you are at cruising altitude, though.

I have only used the mattress with this valve a couple of times, however, I have not had a problem. I always deflate the mattress so the valve is not under constant pressure. Hope this helps.
