Description

Hinomi D3: Cushioned Comfort and Adjustable Support

The Hinomi D3 Ergonomic Office Chair combines a cushioned seat and breathable mesh backrest with TriFlo™ lower-back support, BiPivot™ 5D armrests, a seat-depth slider and recline up to 136°. The adjustable headrest is included. Choose Black, Gray or Khaki for your home office or workplace.

HPS Fit Guidance

Hinomi suggests a height range of approximately 5′1″–6′. Use this as a starting point: the 16.93"–20.47" seat height, 18.31"–20.67" seat depth and 20.87" seat width should suit your leg length and preferred seating space.

Check that you can sit fully back with clearance behind your knees, stable foot support and a comfortable headrest position. At the shorter end of the range, the minimum seat depth may still be too long for some users. A separate under-desk footrest can help when your working seat height leaves your feet unsupported.

Support and Adjustments

TriFlo™ Lumbar and Sacral Support

TriFlo supports the lumbar and sacral regions with separate contact areas. Adjust its height to place the support where it feels comfortable; the pivoting pads accommodate changes in your sitting position.

BiPivot™ 5D Armrests

Adjust height, width, depth and rotation to position the pads under your forearms. The dual-axis design offers 360° pad rotation and 270° joint rotation, giving you different positions for typing, reading or using a tablet.

136° Recline and Included Headrest

Person reclining in a gray Hinomi D3 chair with adjustable headrest

Recline up to 136° to change position between tasks. The auto-tilt tension mechanism provides responsive resistance as you lean back. Adjust the included 2D headrest in height and tilt for comfortable contact when reclining.

Cushioned Seat and Seat-Depth Slider

The foam cushion offers a padded seating surface beneath the mesh backrest. Set the independent seat slider for your thigh length before adjusting the recline. The polypropylene and glass-fiber frame sits on a chrome-plated iron five-star base.

Frequently Asked Questions

Does the D3 come with a headrest?

Yes. The D3 sold by Healthy Posture Store includes the headrest with height and tilt adjustment.

What should I check before ordering for a shorter user?

Check the minimum seat depth as well as seat height. You should be able to sit against the backrest without the front edge pressing behind your knees. A footrest helps with foot support but does not shorten an oversized seat.

Is the D3 seat all mesh?

No. It has a foam-cushioned seat and a breathable mesh backrest.

How should I set the seat depth?

Start upright with your back against the backrest. Move the seat until your thighs are supported and there is clearance behind your knees, then check that your feet have stable support.

Will the armrests fit under my desk?

Compare your desk’s underside clearance with the armrest height from the floor, listed as approximately 24.80"–31.89". Desk drawers and aprons can reduce clearance.

How should I choose between D3 and Nest?

Compare the seating dimensions and adjustment feel. D3 offers TriFlo lumbar and sacral support, 5D arms and an included headrest; Nest offers 3D arms and a choice of headrest configurations.
