Is this one layer or 2?

its one layer thats connected in the front, and the heel has a gel section in the middle that gives alittle..very comfortable..does make you taller..if you are wearing regular shoes that make you taller, plus the lifts, its a significant height increase...good luck

There are two layers per lift, I can choose to use just the one or add the other for more lift

It is a two layered product so you have two height options. I had a difficult time getting the layers back together once I separated them.

I think it's one. I ordered it last April but ordered two so I'm sure I ordered the second as a spare. The price is two low to be for two also the description says 1.

It's an encasement. I already have an encasement for my bed, but applied a 2nd layer to bed due to a toddler sleeping with us.

Uhhhh, it's actually 2 peices. Not sure why people are saying it's only one. Maybe because it fits together like 1 peice. But no, it's 2. The inner part is silicon, and the outer shell is a tough plastic.

You don't need two layers for any kind of protection. we used one with no problems.

I don't think so. The sides are quite thin, so I think it is a single layer. Too thin for me that is why I sent mine back

it looks like one filter but in actuality there are a few there layered. I just took them out and used the ones I thought looked the same. I found my model number on the back of the vaccuum on a silver label under where the cord wraps.

They mean double as in 2 (small) people. This item only has one layer of nylon. I am very happy with mine and would highly recommend it. Hope this helps.

It is one layer, like a shirt. Not very warm unless you layer up beneath it.

I really don't know. I have always used 4 and never thought about using 2. I don't know why you could use just 2 though.

Not if you use to many layers. ONe or two should be sufficient. I plan on doing it this spring.

The one I got was a one piece unit. It is one part not 2. I don't imagine it being sold as 2 piece set.

I think it was 2. I ended up throwing it away. It did not work well at all.

Yes, you can use just one layer. Just remove the empty tray and put the lid back on.

I am not sure how many layers but to me they are way better than the ones that come with the Alva baby diapers. The Alva ones are very thin.
