Question: where can I get a valve for the Downy airbed?
Document: Intex downy full airbed, We are really sad  about the poor quality that we could never image, the first night we used it, one strip of the air bed pumped up, it wasn't flat any more, it looked like a small mountain and rediculars. Really poor quality, stay away from it.
I know you get what you pay for but WOW. These mattresses are just plain awful. Please again do not waste your money on this airbed.
We thought the leak  was in part due to the small rubber gasket not fitting properly. And, like other reviewers, over the course of the next few months, whomever uses the airbed ends up sleeping on a collapsed plastic tarp on the floor in the middle of the night. Mine did not come with a pump, so I don't have any issues with that.Buyer beware. You may get lucky with a perfectly fine airbed, as some seemingly have. Or you may not.
This is a really nice airbed, perfect for camping and for company! It pumps up easily and stays firm for a long time. We will get quite a bit of use from this airbed for sure!
I have tried multiple differenent air mattresses and differnt price ranges, and these are actually the most comfortable and the most durable. Will it last for ever, no, but the price is right, and they have lasted longer than other beds I have tried. I would also say that the classic downy is the most comforatalbe air bed out there. I also have used the queen size.
This air mattress has done a super job all summer long. I have used it over 10 times putting air into it and taking out for guests to stay and sleep on. And everyone loves it, the Downy feel crushed velvet on top is a plus and nice and soft. It holds air really well, no leaks even with 2 -3 people laying on mattress.
We use this often. For sleepovers, for travel...it is a perfect sized double bed. I bought a set of sheets for it. But the top part is very soft, and you probably don't really need sheets. We used it for a week straight for my 6 year old while on vacation, and it did not need to be reinflated at all while we were there. It also deflates easily. You just have to unscrew the valve.
After inspecting the bed, I found no air leaks or holes. So I thought to myself, "eh, maybe I should just tighten it until it's extremely hard to turn the valve," so I did. I've been making sure to tighten the valve fully, and I no longer experience any air loss between nights. Also, watch out for the pop in cap, it can go in snugly, but that doesn't mean it's pushed in all the way.
I did not have success with this product. I was able to inflate it with the reverse air on my vacuumn cleaner and tighten the intake nozzle. However, the next morning the mattress was half flat. The following night I re-inflated, made sure the valve was tightened completely and woke up the next morning to a completely flat mattress. I am returning for another and will try again. If I can keep it inflated I will be satisfied with the product.
I was surprised that this thing would only work with a pump, but luckily I had one. The one-way valve works well when pumping it up. It feels great out of the box. Heavy, plush, but supportive. It won't stay that way for multiple nights of use, but it is what it is, and meets expectations, holds air without leaking, and the velour top holds onto sheets well too. Good for warm weather camping or the occasional house guest.
