It's a niche market. Actually, beds can be much more expensive than that.
A trampoline would be cheaper.

LOL! I agree, You can get a mini trampoline at Walmart that you can keep in your room and jump on for under $20.00. You won't have to worry about breaking that,

And rebounding on a mini trampoline is extremely healthy. It helps drain the lymphatic system.
I have a mini trampoline for already 17 years, I really love jumping on it, but a mini trampoline for under $20.00 one should be careful, as it can harm the knee joints mine costed 17 years ago like $150 and it is very well made, my knee joints are still fine (and sometimes I jump up to an hour or longer, because once I start I just want to keep on jumping

)
