What We Like
- The backrest has a three-level tilt that locks at set angles, with a recline of up to 125 degrees.
- The armrests are listed as 4D flip-up, and the gas lift is described as SGS-certified and leak-proof.
- Rated for 400 lb, it sits among the highest weight capacity ratings in its category, and the listing describes a free parts program.
Watch Out For
- The title calls it a 3D headrest; the spec details confirm height adjustment only, and the headrest angle is not stated.
- Recline tops out at 125 degrees, so it leans back less than chairs that reach 135 degrees, such as the FLEXISPOT ErgoX-PRO.
At a Glance
A locking three-level tilt, flip-up armrests and a 5-year warranty define the CAPOT, a mesh chair with a height-adjustable headrest and 1,366 reviews averaging 4.3.
Who This Chair Is For
- Sitters who like to lock the backrest at set angles instead of letting it float.
- People who switch between upright work and leaning back, and want armrests that flip up out of the way.
Who Should Look Elsewhere
- Anyone who needs to check seat dimensions first: the seat width and seat height range are not listed.
- Buyers who want to lean back further than 125 degrees.
Why the CAPOT backrest locks instead of floating
The backrest has a three-level tilt that locks at set angles, with a maximum recline of 125 degrees. The lumbar support is described as micro-adjust and moves in height. The headrest adjusts in height, though its angle is not stated. Tilt tension, lumbar depth and seat depth adjustment are also not stated.
Alternatives to Consider
Why consider: Adds a stated lumbar depth adjustment and a headrest angle adjustment, which the CAPOT listing does not state.
