Height in a chair is three different tapes, and mixing them up is how a tall person buys the wrong listing. Overall height is floor to the top of the back or headrest. Seat height is floor to the top of the seat. Seat depth is the backrest to the front lip. The grey SITPRO listing is the one in this set that says tall office chair, prints an overall height of 55 inches, prints a seat depth of 24 inches, says the seat depth is adjustable, and describes a waterfall edge. That combination is why this page names it. The maximum on the same listing is 300 pounds.

A person over 6 feet often needs the seat high enough that the feet still reach the floor when the hips are back, and a back that reaches the shoulder blades instead of ending under them. Fifty-five inches overall is the largest height line among the chairs that print a clear height in the item dimensions. MALOL’s 47.24 inch lines are shorter on that same kind of field. The black MALOL home-office listing prints 46.26 inches high. Those gaps are on the listings. They are not a guess from the photos.

Seat depth tells you whether your thigh is supported or whether the front lip lands in the middle of the thigh. Marsail black prints 29.5 inches of seat depth and 21.6 inches of seat height, plus a seat-back interior height of 31.5 inches. That is the longest seat depth in the set, and the seat height is higher than MALOL’s 18.11 inches. The Marsail listing does not say waterfall edge. It does say the seat foam is 3.14 inches thick and the maximum is 330 pounds. If you are tall and your weight is under 330, the long seat is the Marsail number. If you also need the words waterfall edge, that phrase is on SITPRO, whose seat depth is 24 inches, not 29.5.

Seat depth printed on four listings. A longer bar is a longer seat.

The diagram on this page draws four seat-depth numbers as bars: Marsail black at 29.5 inches, MALOL black at 25.59 inches, SITPRO grey at 24 inches, and Cloomey at 21.6 inches. The bars are the listing numbers, scaled to the longest one. A longer bar is not automatically better. Past a certain point the front lip hits the back of the knee. Measure your current seat with a tape. If that tape reads about 24 inches and your knees are already tight, a 29.5 inch seat is a big jump. If the tape reads 20 inches and your thigh hangs off, 24 or 25.59 inches adds support.

Cloomey prints 500 pounds, which is the line that covers a 400 pound reader, and a seat depth of only 21.6 inches. For a tall thigh, 21.6 inches is the short bar on the diagram. The chair can be the right weight and the wrong seat length. Item dimensions are 30.3 inches deep, 22.8 inches wide, and 13.4 inches high. Read the 13.4 inch figure as the listing’s dimension line, not as a substitute for the 21.6 inch seat depth. The two numbers are both on the page and they describe different things.

Adjustable seat depth is a feature the grey SITPRO bullet names, along with a 2D headrest and 3D armrests. The listing does not print the range of that slide in inches. You know it moves. You do not know from the page how many inches it moves. The fixed number you can compare is the 24 inch seat depth. MALOL does not describe a sliding seat on the bullets used here. Marsail prints one seat depth, 29.5 inches, not a range.

Headrests matter when the back is tall enough to meet your neck. SITPRO grey says the headrest adjusts in height and angle. MALOL says a 3D headrest. Marsail’s title includes a headrest and calls the adjustment 2D. None of the listings print the headrest height as a separate inch measurement you can add to your sitting eye line. The overall height is the number you can hold a tape against.

Cylinder height and seat height get confused in product copy. The gas lift is what lets the seat go up and down. A Class 3 line, which SITPRO prints, is a cylinder description, not a seat-height measurement. Marsail’s 21.6 inch seat height is a seat-height measurement. If you are over 6 feet, compare 21.6 inches with 18.11 inches on the MALOL details table and see which is closer to the seat height you already find comfortable. Then read the maximum. Marsail stops at 330 pounds. SITPRO stops at 300. MALOL stops at 300.

The waterfall sentence on the grey SITPRO description is the same idea as on the black SITPRO page: the front edge is shaped to reduce thigh pressure. A tall person feels that edge farther forward if the seat is long, and sooner if the seat is short. A 24 inch seat with a sloped front is a different object from a 29.5 inch seat that does not use the waterfall phrase. You can want both and still have to pick the listing that actually prints the phrase you care about.

Recline ranges do not fix a short back. SITPRO’s 90 to 160 degrees gives a long layback. MALOL’s comparable executive listings say 90 to 130. A tall back that reclines is useful when you lean, and useless if the top of the back still ends at your mid-back when you sit up. Look at the 55 inch line first, then the recline range.

What to do with a tape tonight: measure floor to the top of your current back, floor to the seat, and backrest to the front lip. Write the three numbers next to 55 inches, 24 inches of seat depth, and the fact that SITPRO does not print a seat-height field on the grey listing. Then write your weight next to 300 pounds. If the weight loses, the tall-and-waterfall listing is still the one that says those words, and it still does not cover you. The seat guide is where the 500 and 700 lines are, with their shorter or unlabeled seat depths.

MALOL prints a seat-back interior height of 29.33 inches on the black home-office listing, next to the 46.26 inch overall height. Marsail prints 31.5 inches of seat-back interior height next to the 29.5 inch seat depth. Interior back height is the mesh you lean on, not the headrest above it. Two inches separate 29.33 from 31.5. The overall height gap between 46.26 and SITPRO’s 55 inches is larger because the headrest is in that taller number. Do not add interior height to overall height. They already overlap.

Marsail’s seat length is 23.6 inches. MALOL’s seat length is 24.41 inches, printed beside a 25.59 inch seat depth, so length and depth are different fields on that table. On Marsail, 23.6 is the side-to-side seat length and 29.5 is the depth. If you only keep two Marsail numbers, keep those. The grey SITPRO page prints a 24 inch seat depth and a 22 inch item width, and it does not add a separate seat-length field next to them.

The grey MALOL listing prints 25.59 inches of seat depth in the details table and also carries another line about a 19.7 inch seat and a 17.3 inch seat depth. That 17.3 inch figure is on the grey MALOL listing. It is not the grey SITPRO seat. The chair this page names is the SITPRO grey chair, with a 24 inch seat depth and a 55 inch overall height. Keep 17.3 attached to the MALOL line so the decimals do not get merged into a different chair.

If you are over 6 feet, also check the headrest travel with your hand on the current chair. A 55 inch overall height only helps if the pad meets the back of your head when you sit up, not only when you recline. SITPRO says the headrest moves in height and angle. The listing does not print those inches. The number you can still compare tonight is the 55 inch overall line against a tape from your floor to the top of your current back.

This page did not seat a six-foot person and mark pressure points. The button opens the grey SITPRO chair because that listing is the one that says tall and waterfall edge together. The Marsail photo is not the winner on this page. Its longer seat depth is the comparison bar.
