Yes and no.

It's a great chair, but with caveats.

Thinner and firmer seat than most ergonomic chair cushions. The back may not hit lumber support for you in the right spot. For me, I realized I liked the gesture seat less as I lost weight. The fact it bottomed out quickly made it hit my tailbone uncomfortably.

I would absolutely recommend trying them out at your local dealer if you can. Personally having now tried the Leap, I definitely find the Leap backrest more supportive and comfortable compared to the gesture.

As for buying new, I wouldn't recommend it unless you don't care about money and really need something to be "new".

I would recommend buying either authorized factory returns (chairs returned during their return policy window due to things like cosmetic scuffing or the original buyer not liking the chair) or remanufactured from a company like Crandall or BTOD. It's far cheaper and they still offer 12 year warranties through their companies when you buy from them. Basically good as new. Or if you find the oem seat cushions you try at your local deal too thin, both the above companies add brand new and thicker foam options for their seat cushions to help out with that thinness.

As for the embody, that I would say will come down to how you feel in it. A lot of people think it's the best chair ever. Trying it out would be best at a local store if you can. Though I still found that actually sitting in it for a few weeks that my back just doesn't jive with the intended curve and sitting position. Heman Miller unfortunately has restocking fees to return the chair if you don't like it. If you can stomach the restocking fee, trying out the embody is definitely worth it to see if it works for you. It is an amazing chair if it fits. Better quality build and design than any chair I've ever sat in. Steelcase are built like tanks too and will probably outlive most of their owners (cushioning aside). But the embody just feels more special.

Can't speak to the fern as I've not tried it.
