Have a Fern. I hate it. I wish I kept my Aeron. The arms are the worst. Unlike the Aeron, where I could slide the arms up and down and lock them in place anywhere along the way, the Fern arms have predefined settings that are either a bit too high or a bit too low for me. It's enough to cause shoulder pain. The chair also squeaks a lot. And the seat is very firm but I loved the Aeron mesh seat. FWIW, I'm 5'7.

ETA: Check the return policy before you buy the Fern. I bought mine in December, 2020 and had to buy it from one of Hayworth's resellers because the config I wanted wasn't available directly from Hayworth. Resellers at that time, at least, had a no return policy.

I've had the same OXO soft grip model since 2003 and use it several times a week. Mine is as good as new.

There are massive sales in January too. Retailers want to get rid of all the stuff that didn't sell over the holidays.

Another friendly PSA : This is why it's best to always pay with credit cards instead of debit cards. I mention this because so many people pay with debit. At least with credit cards, it's the bank's money and the bank will likely wipe the charges. When a debit card is compromised, it's your money that was spent. Good luck getting that back in a timely manner, if at all.

If it’s so bad, why are you eating there?
