No. I have never heard of one that does. The actually brakes are what have a spring in them

Yes it has the spring. It is ready to be installed right out of the package. It has a solid feel and performs well.

Yes since it is in fact spring loaded all you would have to do is to unload the spring. When you first receive it there is no pressure on it.

I believe this one has one spring. You better have some muscles on your arms before you buy this one though! I could not even push it down 2"! The first one I had about 20 years ago did not have all of the features this one has. If you have the strength and want to buld your body all over buy this one. It will work!

No springs. Those are "structural air pockets" which allow the air mattress to better support and distribute weight better than just a simple empty air bladder.

It does not have springs and I do not recall if the bar was adjustable or not. It was not very bouncy because it does not have springs.

The one I received didn't come with the spring, but it was not difficult to reuse the existing spring

It does have springs inside. Not sure how small it will fold up (ours is on a sleeper-sofa), but probably a slightly larger bag than traditional queen air mattress

No the spring does not come with it and I don't know where you would find one or maybe amazon has one that you could order.

I'm sorry to say I don't know if there are springs it! It's pretty comfortable for a sofa bed though. We don't "fold" ours up, just deflate it and push the sleeper couch back in. Our 7 yr old grandson does it!

no this keyboard has springs not weights. and playability is awesome. Highly recommend in investing in one for playing piano.

Yes, it does. I wanted one with springs. I have heard that the bungee course breaks or wears out on the others. The springs also bounce more.

Yes the inner spring mattress has springs in it. The foam mattress is made of foam and has no springs.

Yes! It doesn't spring open like it did before but it opens with no problem.

Yes it does have a spring load bar, plus there is a metal clip that holds the bar in the middle for extra support.

No, it doesn't have any springs. The backrest does not adjust once in place. I find that I can only lean back into it when I am biking downhill. Going uphill you have to bump forward and sit on the seat normally. BTW- my bike is an adult tricycle.

It does not have springs, but it doesn't need them. It's a great device that you manually turn the large plastic knobs. I make it a little tighter about three times, slowly draining the tofu. It takes only about 20 min.

Sorry for the late reply. Yes it has the SPRING logo on the top right of the screen.
