How many springs does it have?

I really haven't got the slightest idea. But it's held multiple teens. Granted, they are all skinny, but the cumulative weight must be considerable - at least 270 pounds, maybe more.

There aren't any springs. You don't go very high when jumping. But it is very sturdy. We are happy with it.

I cannot remember the spring rates. There are 2 firing springs in the kit. One is considered the competition spring and it produces a very light pull.

no. it just has side boards. However, if you put in your own cross board in the middle, you could put in 2 box springs.

I don't know....can't see the inside. Most springs are metal I believe.....

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.

There are no springs. It's a simple butterfly screw and threaded metal rod setup. The only way to adjust the distance between the plates to press the Tofu harder is to shorten the distance between plates by tightening the screws.

There's one firing pin spring,one trigger spring that you don't have to use and two springs for your safety plunger/extractor. It's awesome and easy to install

I see that someone answered that it is a round spring. Since I bought this as a gift I do not know.

I am not sure what spring is in it but this is designed as a direct OEM replacement. I am at 17.5PSI with no issue whatsoever.

Yes it has springs. But honestly, I would go with a different brand. I have had this trampoline sitting in PIECES in my livingroom for almost 3 weeks because it came with defective parts and missing hardware, then the company sent me the wrong parts, and they told me on Friday that they did 2 day shipping for the missing hardware and replacement pieces, and I still have not gotten it. If you arder this one, I sure hope you get all the pieces and they all fit, so you dont have to go through what I still am going through!!!!!

It does have a single spring. I have had no problems with it, in my Gen 4 Glock 19. Hope that helps.

I've had mine for 3 months and three springs have broken. I use it every day for 30 minutes, but am way under the weight limit (I'm 145 lbs).

Two. Nice kit, rattles a bit unless you tighten it up enough to keep tension on it.

It does not have springs. It is a little more than a platform. It does have enough bounce to it to do flips

Yes it has a spring. Been played with by my kids and husband for three months and its not broken yet. They dont hang on it tho.
