what are the dimensions? Does mattress slide down after awhile?

Since the previous answer gave the dimensions I won't do that. I am using the wedge on a daybed and have them stacked. Pushing the wedge further under the mattress seems to raise it more. Sometimes it scoots back up to the edge, but it doesn't take anything to scoot it back down while making the bed. As far as the mattress scooting, like I said it's a daybed.

Each wellness wedge is 22 inches wide by 18 deep and approximately 3 inches high. They are stackable if you want more height. I have not had any issue with the mattress sliding off the wedge or the wedge sliding from under the mattress, but I have not stacked them to go over the 3" height.

I measured the dimensions as approximately 22" X 16". One set raises the head of the bed by 2". We have a king size bed and actually ordered three sets of two lifts each to raise the head of the bed by 4 inches. The lifts fit across the width of the bed fine and raise the head by 4 inches. We did not experience sliding downward. However, after trying this approach for six weeks, we have removed one set of the lifts so that the head is raised by only 2 inches. At 4 inches, I began having lower back problems and neither my husband or I slept very well. It doesn't accomplish quite what I need for acid reflux symptoms, but we do sleep better.

The wedges are big enough for the head of my queen bed. You would need 2 sets if your going to stack them. The mattress does shift after a few nights but if you make your bed every day, it should be easy to reposition the mattress.

I bought a king size, so sorry, can't help. Perhaps email the company (manufacturer, not seller) or google the product name for dimensions? Dorm mattress tend not to be too thick, but the extra length may be an issue. I don't know. Sorry.

Unfortunately, I gave this as a gift and do not have access to the mattress or the dimensions, wish I could be more help. Good Luck.

I don't know the exact measurements but it did fit all the way to the edges of the bed. I have seen some that fall about an inch short all around. My husband finds it to be very comfortable. I have fibromyalgia and I never sleep well on any mattress regardless of firmness etc.

Anthony, I don't remember the actual dimensions. It's a queen size that goes all the way to the floor UNLESS the bed is a very tall one OR if there's a thick foam topper in addition to a regular mattress. It's very light weight. Hope that helps. Other sizes are available.

I'm not sure of the exact dimensions, but I can tell you we put ours in our camper and it hangs over just slightly more than the mattress that came with the camper. The bed area is also a part of the slide out which it can not be any larger than a standard queen sized mattress. Hope that helps. Oh and this mattress is SUPER comfortable!!!!

Im not sure of the exact dimensions, but its just a regular twin sized bed, about 6 inches thick. Its great for a single person that is under 6 ft tall(or over 6ft tall if you like your feet sticking off the edge like me)

I'm not sure about exact dimensions, but it's the same size as my son's crib, and a standard crib mattress fits it. So I wouldn't say it's larger than the average crib. I'd say it's standard crib size (not the mini-cribs, of course). We've been using this crib for over 3yrs now and still love it!

The box it comes in is approximately 18 x 15 x 8 (in inches). Not sure how difficult it would be to get the mattress back inside the box because it is a tight fit, but that should give you a rough idea of its deflated dimensions.

The mattress I have is 31/2 inches. Be aware this mattress is heavy though, nearly 3 pounds, it does deflate and fold down small, just isn't that light.

I do not know the exact demensions. I ordered the full size and yes it is a little bigger than the full size mattress I previously had but all my sheets fit it and it fits the frame. Its deeper and I love it

I can't give the specific measurements, the bed is in another State. Won't be going back there for a couple of months. Sorry.

84"x36"x6" The bed is great but mattress not so great. Spring protruded from end seam and caused a wound.

5 1/8" thick or less, according to Ikea. I bought this one (http://www.amazon.com/gp/product/B00GO8Y6BQ/ref=oh_details_o02_s00_i00?ie=UTF8&ps;c=1) and it is comfortable and safe for my 3-year-old child. I did have to put a rolled up blanket at the end of the mattress to make it more snug.

Hello. I don't have the board any longer but the piece that goes under the mattress is large enough that it cannot move. I am guessing that it is about 12" wide by 20" long.I can tell you that it was a GREAT help for my husband.

I don't remember the exact dimensions. It was compressed so it was about half the size of the actual mattress.
