Will this work under a Naturepedic Mattress (http://www.amazon.com/Naturepedic-Compromise-Lightweight-Firmness-Mattress/dp/B004IPL?

Yes...the sensors are extremely sensitive to any movement above the mattress, including wind movement from ceiling fans in the room.

Yes. These are very sensitive. We have to shut off the ceiling fan when we turn this on because it picks up the fan blades moving.

Yes, this will work well with a foam mattress, I bought this in combination with a Sleep Innovations 12 inch memory foam mattress and there is no support issue, the supports are not slats, but more of a grid pattern that leaves no room for sagging.

I'm not sure what manufacturer would say but I can't see any reason that it couldn't. It stays put on the mattress but not so tight that it wouldn't accommodate a mattress protector underneath.

It will work, but I'm warning you this bed is not what everyone says unless you like an extremely firm mattress, thought I would give you a warning!!

I suppose you could put it under a very light weight twin size mattress but it would not work very well. Maybe the 12 inch model would work better but since it is not as wide as the mattress the mattress may tip from side to side.

I don't think this will work for you, Patricia. The manufacturer says it won't work with lightweight foam mattresses so I doubt an air mattress would have enough weight to hold it in place and it would be dangerous.

Hi Dan. it depends how thick your memory foam mattress is. if it is normal thick it should not be a problem. I have these thin Ikea mattresses (5 inch thick) and you can feel the slats under you... I need to put a set of special Ikea slats under my mattress so that it will be comfortable or double up on the thin mattress, then it is no problem. Hope this helps.

It's possible! It depends how firm your mattress is in comparison to the topper. If the topper is softer than it will help! The topper is pretty firm but it contours to your body.

I don't think it would work with the mattress below the side boards. This item needs to be between the mattress and box spring.

Yes, absolutely. We have many customers who have used Mattress Helper on this type of memory foam mattress and are quite happy because of it. Purchase 2 of the 20" for full coverage under your mattress. Thank you.

It should be fine because the metal frame that goes under the mattress is a solid piece that has a cross bar. What goes under looks the same as what you see on top, only it is longer - very stable. This is a good product that is very helpful for getting in and out of bed and when standing.

I put the bed bridge between two twin mattresses & under king-size mattress pads without any straps! It stays is place and I can't feel the gap at all, so it should work for you under your mattress. It really does seem to bridge that gap eventhough it's soft & flexible. It was the best small investment I've made recently, so I hope this info helps you.

If you put lay plywood on top of the box spring, it works fine. I believe it has to have a solid surface (the plywood) under it for the warranty to be good. We have two foam matresses..one tempurpedic and,the Dynasty, and both are on box springs covered by plywood. We love the Dynasty mattress.

I'm not a home right now, but we have a double bed and I believe you should be able to put two under the mattress without any problem. My husband really like this one.

I do not know how placing this foam under your mattress will work for you. If your mattress is soft then it will still be soft if you place it on a piece of plywood. This foam will prevent a soft mattress from bottoming out on a hard surface. This foam is great for a mattress on it's own.

I agree with Barbara that if you do try to use it under the pillows, you cover it with something first. My guess is it will still work better under the mattress, because it does tend to shift a bit over time, and that will be worse with less weight on it.We haven't had problems with leakage, though, and except for resetting its position from time to time, the genie has worked quite well for us.

It should. There is elastic around the bottom of the sides, hope that makes sense, so just tuck it under the mattress.
