I used to ride a Cheeko 90, which looks like a vintage metal tractor seat, except with padding.
I found it to be a superb bicycle seat and had absolutely no problems keeping lateral conrol of my bike.
However, while the thing looks good when new, in charcoal grey cloth reminiscent of MBtex, the cloth wore patchily in a couple of years and the vynil surround was vulnerable to anything rough or sharp it came into contact with. I replaced it with a Brooks B73, not because the Cheeko was in the least unsuitable or worn out, but because it had become cosmetically untidy, and the Brooks cost less than recovering the Cheeko90 in leather, and I wanted to experiment with Brooks because I never had one before and it was on sale at SJS.
I just liked the Brooks so much that I never returned to my fallback plan, recovering the Cheeko in leather.
The first class gubbins under the cheap covering:
In my opinion the Cheeko90 was the best of the bicycle seats, a boon to people with bad backs and haemorrhoids and pressure on unmentionables and whatnot complaints about bicycle saddles. But the quality of concept and base construction wasn't matched in the soft furnishings, and the marketing was a mess. It is no surprise that this fine seat is no longer on the market, or that secondhand ones go for high prices. It works, and is worth recovering with a more lasting material.
