I needed a work-from-home chair (+gaming on the weekends) that could ergonomically & comfortably get me through 4+ hours straight of sitting. While at work, I'm used to sitting on a Steelcase Leap V2 chair (which is a 5 star in the $500-$1000 range for comparison), I knew I personally could only afford <$500 (<$300 ideally) so this CLATINA nailed the price-point. By dropping to this price-point, I was well aware that I would have to sacrifice major features, though I searched in hopes of finding a chair that would minimize my sacrifice... and I believe I found an excellent option![For reference, I am 5'8" with relatively short leg to torso ratio]FIRST, I'll list the features of high-end ergonomic office chairs included (with their caveats):+ Fairly thick cushioned seat (a little stiff, no anatomical 'sculpting')+ 'Waterfall' cushion design by knees to prevent circulation cut-off+ Sliding seat for adjustable depth (not designed well to be as useful compared to high end chairs, which have a deeper seat length to accommodate the sliding forward. With the CLATINA, the seat depth is shorter and I imagine for those with longer legs, their butts would begin to "fall off" the back of the seat when the seat's fully slid forward. It's perfectly in range for me)+ Lumbar support using ~1 in of dense foam (I've got it set at it's highest setting and it hits me just right. It can go lower, but not higher, which I imagine more useful for those taller than I am)+ Adjustable seat height (it can go plenty tall, though I'm at its lowest setting and it's barely perfect. I really could go ~0.5" lower, and I imagine those shorter than I am would not be able to get their feet flat on the ground. Most chairs can't really go this short, which is why buying an elevated foot rest is an option for shorter folks)+ Extreme tilt back angle; I can nearly lay down flat! (however, no compensating seat angle tilt)+ Adjustable seat tilt tension+ Adjustable seat tilt stopping angle+ Arm rests have in-out adjustment option (which was really important to me)+ Arm rests are height adjustable (I’m at the highest setting and it’s just perfect. Again, I’d imagine someone taller may need a little more height rather than being able to go really low… though when adjusted to the lowest setting, the chair is able to slide under desks!)SECOND, I’ll list the features sacrificed (that weren’t already discussed within my caveats):- Arm rests do not adjust back-forward. Unfortunately as a result, my hands to not fully clear the arm rest so that I cannot type, etc without the arm rest half getting in the way. To compensate, I have to lean my upper body slightly forward or move my arms forward (which deviates from ideal ergonomic body positioning)- Arm rests not cushioned.- Seat cushioning does not compare to higher end chairs. (It’s a big step up relative to my previous ~$100 home office chair, but I don’t expect miracles)- Seat backing is fine, but not amazing. It may stretch out over time and become less supportive- I received no assembly instructions (though a decent User Manual)THIRD, packaging and shipment+ Box was branded and constructed well+ All parts came packaged VERY nicely, separated as star base, seat (with arm rests attached), seat back, and pneumatic seat post. Hex wrench and 2 bolts (plus extras) can included. All that considered, it was very easy to assemble without instructions.+ My chair arrived VERY quickly, faster than estimated delivery times. I'm exceedingly grateful.In summary, this chair satisfied most of my ergonomic needs and I believe its construction will last me many years. At this price point, it’s a definite 5 star. If some of the caveats and missing features I listed are required for you, then I truly believe you’ll have to pay more for a different chair (though hopefully not too much more!).
