How stiff are the coils? I.e., can you really feel it pulling when you move your arm so that the coil stretches?

They are loose, pulling them provides little to no resistance and it still coils back up
350583
Nope;coil wire is light guage enough where you don't feel any resistance at all;very comfortable.

not stiff at all. they offer almost no resistance then recoil back to their original form. more than 3 feet and then maybe you can start feeling some pullback.

With springs you can usually feel the coils when you lay down on the mattress or sit on it. Unless it has a top cushion on the spring mattress, the springs are very obvious. The memory foam has a more "consistent" hold to it where it doesn't bounce as much as the spring and is often much more comfortable. Go to a local mattress store and lay on the memory foam beds. You'll feel the difference. Also the mattress you have asked the question on- it is also a pretty good and inexpensive mattress that feels awesome on the back and joints. Anyways good luck.

Mine was a little stiff at first as well, but make sure you're using a twisting motion more than a sliding-up motion.

I don't know exaclty, nor it is on the specs (as far as I know).Anyway, the minimum tension is quite "soft" (even for a usually non-powered pinky finger, for example) and it is widely adjustable...Hope this helpsBest regardsGiancarlo

The higher the level you place the tension, the better pull and push the workout will be. I started on level 2 to getuse to the machine, and have upped it to now level 4. I feel the pull in my arms, legs, bottom,and alittle in my stomach. I feel the forward movement inmy arms and shoulders. I really feel this is a good workout. I go slow for awhile, then pick up the pace and then slow it down again- sorta like they do in cross training. I also move my hands holding the bar to gripping it over the bar and then switch to holding the bar gripping under. I hope this helped you decide. I love my workout. And its such a great price.

It wasn't for me but it's nicely quilted and I wouldn't think you could feel it. I had one before and didn't feel the coils. In fact I'm going to buy another one like this for myself for winter.

No, the coil is not fixed so it does move a little, max 1/2 inch. The widest part is 1 1/2 inches. We have used this since DEC 2012 and have had no concerns.

It's a little stiff... push and pull where the arrow indicates to do so. You'll have to apply a little more force than what seems necessary. The plus is that you won't have to replace the batteries very often because they last a long time!

It depends on the amount of pressure generated with the amount of twisting. You should only feel slight pressure--if you are feeling pain, then you need to back the pressure off with the twisters--the amount of pressure can be regulated that way.

Yes, you can feel the coils. We put a quilted mattress pad over it, at that point you can't feel them.

There is no stiffness. The material is entirely soft, but it compresses your hands slightly. I'm not sure it would stop clenching--you can still make a tight fist in these.

It's pretty flexible... I could coil it in a 6" diameter tube pretty easily without it kinking. In warm weather, the material gets softer and more flexible too. The only rigid parts are where the emitters are, which are about an inch or two long each.

It comes in a very tight coil. So with that being said yes it will flex to what you want it to do.

Hmm. It seemed like mine loosened up once it was a little warm. I'm not sure though. Did you ask the distributor for feedback?
676244
No, it is not the coils that make the difference of shading or lining, it is the pressure off the spring arm, you will need to adjust accordingly, they sell a little tool you can use to measure the tension.

I don't find it difficult to push at all. It has really good suction, though, so pulling back requires a bit more force. A normal, healthy adult would have no problem with it. Someone with musculoskeletal issues might feel,a bit of strain.
