1. Ergonomic Kneeling Chair with Backrest, Improve Posture, Thick Cushions, Locking Wheels for Home & Office, AKONI 512B (Black) — Smallest listed footprint
Listed details: dimensions 22″ D × 18.5″ W × 25″ H; item weight 27.9 pounds; listed maximum weight 250 pounds; material Faux Leather, Iron; color Black.
This is a black kneeling chair with a backrest on wheels, in faux leather and iron. The listing gives 22 inches deep, 18.5 inches wide and 25 inches high, a footprint of 2.83 sq ft, the smallest of the three. Seat height adjusts from 23 to 27 inches with a single side lever, and the casters have manual brakes. The seat is listed at 16 inches wide and 12.5 inches deep, with an 18 inch kneeling pad width. The item weighs 27.9 pounds, the maximum weight recommendation is 250 pounds, and the listing describes thick cushions.
Pros
- Smallest footprint of the three at 2.83 sq ft
- Seat height range (23 to 27 inches) and a single side lever are stated
- Casters with manual brakes are listed, and the seat is stated as 16 inches wide
Cons
- Heaviest of the three at 27.9 pounds, which is 19.9 pounds more than the Sleekform (27.9 − 8)
- Rolls on casters, so the manual brakes have to be set to keep it in place
- Faux leather cover, and no care information is given in the data
Who it is for / who should skip it: Pick it if you want a stated height range, a quick lever and the smallest footprint. Skip it if you want the lightest chair to carry.
2. VEVOR Ergonomic Kneeling Chair, Wooden Posture Knee Chair with Adjustable Thick Foam Cushions, Backrest and Wood Frame, Adjustable Height, Relief for Neck or Back Pain for Home, Office or Meditation — Largest listed footprint
Listed details: dimensions 38.7″ D × 21.2″ W × 33.8″ H; item weight 22.4 pounds; listed maximum weight 265 pounds; material Multi-Layer Board + Foam + Linen Fabric; color Beige.
The VEVOR is a beige kneeling chair with a backrest, thick foam cushions and a rocking base. The listing gives 38.7 inches deep, 21.2 inches wide and 33.8 inches high, a footprint of 5.7 sq ft, the largest of the three and about twice the first chair’s 2.83 sq ft. Height adjusts with side screws, unlike the first chair’s side lever. The materials are listed as multi-layer board, foam and linen fabric, and a bullet describes a solid wood frame. The item weighs 22.4 pounds, the load capacity is 265 pounds (120 kg), and the seat depth is 11.6 inches. Bottom strips add grip.
Pros
- Highest stated load capacity of the three, 265 pounds (120 kg)
- Rocking base and bottom grip strips that the listing says help limit sliding or tipping
- Thick foam seat and kneeling pads with a linen fabric cover
Cons
- Largest footprint at 5.7 sq ft, about twice the first chair’s 2.83 sq ft
- Height adjusts with side screws, and no height range is stated
- The title says wooden, the specs say multi-layer board and a bullet says solid wood, so the build is described inconsistently
Who it is for / who should skip it: Pick it if you have open floor under the desk and want a rocking base and the highest stated rating. Skip it if you need a compact chair or a quick height change.
3. Sleekform East Austin Kneeling Chair with Back Support – Boucle, Natural — Middle listed footprint
Listed details: dimensions 28″ D × 22″ W × 21″ H; item weight 8 pounds; listed maximum weight 250 pounds; material Boucle; color Boucle With Back.
The Sleekform East Austin is a boucle-covered kneeling chair with back support in a modern rustic style. The listing gives 28 inches deep, 22 inches wide and 21 inches high, a middle footprint of 4.28 sq ft. It weighs 8 pounds, the lightest of the three, and the maximum weight recommendation is 250 pounds. The seat depth is 12 inches. The bullets describe a forward-tilted seat, an open hip posture and a height-adjustable frame. The data does not state the adjustment range or method, whether it has wheels, or the seat width. Its listed color name is Boucle With Back, and the title says Natural.
Pros
- Lightest of the three at 8 pounds
- A 250 pound maximum weight recommendation and a stated 12 inch seat depth
- Forward-tilted seat with a boucle cover in a modern rustic style
Cons
- The height adjustment range and method are not stated
- The data does not say whether it has wheels or a rocking base
- Takes 1.45 sq ft more floor than the first chair (4.28 − 2.83)
Who it is for / who should skip it: Pick it if you want the lightest chair with a soft boucle look and can confirm its height range. Skip it if you need stated wheels or a stated seat width.
What to check before buying kneeling chair with backrest
Start with the footprint, because a kneeling chair’s base is longer than a normal chair’s. The first chair is 22 inches deep by 18.5 inches wide, or 2.83 sq ft. The Sleekform is 28 by 22 inches, or 4.28 sq ft, which is 1.45 sq ft more (4.28 − 2.83). The VEVOR is 38.7 by 21.2 inches, or 5.7 sq ft, about twice the first chair.
Next, check adjustment. The first chair states a 23 to 27 inch seat height with a side lever. The VEVOR adjusts with side screws and states no height range. The Sleekform lists a height-adjustable frame without a range. If you share the chair or change desks, a stated range matters.
Third, compare weight ratings: 250 pounds for the first chair, 265 for the VEVOR and 250 for the Sleekform. The gap is small (265 − 250 = 15 pounds).
Fourth, look at movement. The first chair has braked casters. The VEVOR has a rocking base with grip strips. The Sleekform data does not mention either. Choose casters to roll between desk and table, or a rocking base if you want movement while seated.
Fifth, compare the seat. Seat depths are 12.5, 11.6 and 12 inches. Only the first chair states a seat width, 16 inches.
Sixth, check weight and materials. The chairs weigh 27.9, 22.4 and 8 pounds. The first uses faux leather and iron, the VEVOR uses multi-layer board, foam and linen, and the Sleekform uses boucle.
Decision rules: choose the first chair for the smallest footprint and a stated height range. Choose the VEVOR if you have the floor space and want a rocking base and the highest rating. Choose the Sleekform for the lightest chair if you will confirm its height range.
Worked example: fit math for these three options
This worked example is our own planning arithmetic from the listed dimensions, not test results. The wall length and walkway width are assumed example values; replace them with your measurements.
Wall example. Assume 36 inches of clear wall.
- Ergonomic Kneeling Chair with Backrest: 36 − 18.5 = 17.5 inches spare; centred, 8.75 inches on each side before trim, plugs or curtains.
- VEVOR Ergonomic Kneeling Chair: 36 − 21.2 = 14.8 inches spare; centred, 7.4 inches on each side before trim, plugs or curtains.
- Sleekform East Austin Kneeling Chair: 36 − 22 = 14 inches spare; centred, 7 inches on each side before trim, plugs or curtains.
Walkway example. The US Access Board gives 36 inches as the minimum clear width for an accessible route. That figure is a yardstick, not a rule for private homes. To keep 36 inches clear beside each product, the walkway between it and the opposite obstacle must be at least 36 inches plus its depth:
- Ergonomic Kneeling Chair with Backrest: 36 + 22 = 58 inches of total path width.
- VEVOR Ergonomic Kneeling Chair: 36 + 38.7 = 74.7 inches of total path width.
- Sleekform East Austin Kneeling Chair: 36 + 28 = 64 inches of total path width.
Footprint. Depth × width, converted at 144 square inches per square foot:
- Ergonomic Kneeling Chair with Backrest: 22 × 18.5 = 407 sq in, or 2.83 sq ft.
- VEVOR Ergonomic Kneeling Chair: 38.7 × 21.2 = 820.44 sq in, or 5.7 sq ft.
- Sleekform East Austin Kneeling Chair: 28 × 22 = 616 sq in, or 4.28 sq ft.
Mistakes to avoid
- Forgetting the long base. A kneeling chair’s base is deeper than its seat. The VEVOR is listed at 38.7 inches deep, so measure the space under your desk.
- Assuming every chair adjusts the same way. The first chair has a side lever and a 23 to 27 inch range, the VEVOR uses side screws and the Sleekform states no range.
- Trusting the VEVOR material label. The title says wooden, the specs say multi-layer board and a bullet says solid wood. Check before you count on a solid wood build.
- Ignoring how the chair stays put. The first chair rolls and needs its brakes set, the VEVOR has a rocking base with grip strips, and the Sleekform data is silent.

Frequently asked questions
How much space does a kneeling chair with a backrest need?
Listed footprints range from 2.83 sq ft for the first chair (22 by 18.5 inches) to 4.28 sq ft for the Sleekform and 5.7 sq ft for the VEVOR. A kneeling chair’s base is longer than its seat, and the VEVOR is listed at 38.7 inches deep, so measure the space under your desk first.
How much weight can these kneeling chairs hold?
The VEVOR lists a 265 pound load capacity (120 kg). The first chair and the Sleekform both list a 250 pound maximum weight recommendation. The 15 pound difference (265 − 250) is small, so the choice is more likely to turn on adjustment and base size than on the rating.
Can you adjust the height of a kneeling chair?
All three are described as adjustable. The first chair lists a 23 to 27 inch seat height with a single side lever. The VEVOR uses side screws, and the Sleekform lists a height-adjustable frame. Neither the VEVOR nor the Sleekform states a height range in the data, so check it against your desk before buying.
Do kneeling chairs with backrests have wheels?
The first chair lists casters with manual brakes. The VEVOR has a rocking base with bottom grip strips instead of wheels. The Sleekform data does not mention wheels, so check its listing page if you need to roll it. Brakes or grip strips matter because they limit sliding.
