Question: Does this seat cover have the space in the middle or is it  full all the way through
Document: This seat cover was way too small for my stationary bike, so I had to return it.
Needless to say the seat was slick and cold on the way home. As mentioned above, the easy fix to this problem is remove the seat cover and take it inside with you.
My gym purchased new spin bikes and even though I've been spinning for a while and had no issues on the old bikes,  I just couldn't get used to the new seat. My tush would hurt 1/2 way through class and be sore for days after. This seat cover is awesome. Now I can spin again pain free :)
This seat cover is perfect for spin class. I got it on Friday and used it at my spin class today (Tuesday). My rump did not know what happened because it was almost a pleasure to sit on the bike today. The seat cover is full of gel and it offered lots of cushion. The cycle seat was still narrow and a little uncomfortable but this seat cover made a world of difference.
I use the seat cover on a Schwinn exercise bike and ride it about 5 times a week for 20 minutes. I put a towel on it so that i don't have to wash it, so the failure is not from washing. Basically the gel pad has split in half in the middle and leave a big gap in the gel cushion right about where you sit. I would have thought it would last more than 8 months before failing.
This will not fit a Schwinn exercise bicycle, and I saw mixed reviews to that effect, so being optimistic I tried, but there was no way to get it to fit. May work for a bike, but not an exercise bike.
Not as good as I thought of it will be, but it is okay. I would settle for a better seat cover.
Easy to fit, remove and wash gel seat cover which makes your ride more comfortable.
I am really  pleased with the double gel seat cover. It gives me  the protection I was looking for .
I bought this to cover a rather hard bicycle seat. It has made a big difference in comfort on my bicycle.
Answer: yes
