Herman Miller Aeron vs Kokuyo Ing Cloud: Which Should You Buy?

Introduction

The Herman Miller Aeron and Kokuyo ingCloud are both mesh task chairs with different approaches. The Aeron comes in three sizes with a suspension seat and back and lumbar options including Adjustable PostureFit SL; the ingCloud has a frameless 3D Hammock Mesh back and Triple Gliding at the seat, backrest and armrests. This is a research-based comparison using manufacturer sources, not a hands-on test.

At a glance

Herman Miller Aeron—strengths & weaknesses

Documented features: Herman Miller sells Aeron in sizes A, B and C, with weight capacities of 300, 350 and 400 lb by size, the Harmonic 2 tilt, arm options up to Fully Adjustable Arms, and lumbar options including Adjustable PostureFit SL. Herman Miller does not offer a headrest.

Check before buying: Choose the size first: seat height is 14.4–19.3 in (size A), 14.8–22.8 in (size B) or 15.8–22.8 in (size C), and seat depth is fixed by size. The US Herman Miller Store lists Aeron at $1,775–$2,840 depending on configuration; Herman Miller lists a 12-year, 3-shift warranty. One owner found the seat pan dug in, so try the size you would order.

Kokuyo Ing Cloud—strengths & weaknesses

Documented features: KOKUYO lists a 3D Hammock Mesh backrest without a separate lumbar adjustment, Triple Gliding at the seat, backrest and armrests (gliding range adjustable in 2 steps, no recline angle published), a Front Free Tilt seat front instead of seat-depth adjustment, and arms that adjust 80 mm in height and pivot inward.

Check before buying: Choose the type before ordering: the headrest comes only on the w/ Headrest type and cannot be retrofitted. KOKUYO lists a seat height of 425–495 mm (16.7–19.5 in), a 10-year structural-frame warranty and no user-weight rating. KOKUYO's Japanese store lists ¥246,180–¥268,510 (tax included); confirm delivery and service outside Japan.

How they differ

The Aeron relies on 8Z Pellicle mesh zones and lumbar options such as Adjustable PostureFit SL. The ingCloud uses a frameless 3D Hammock Mesh and Triple Gliding designed to move with you; its lumbar support comes from the lower part of the mesh back, with no adjustment.

Seat height: Aeron's seat height depends on size (14.4–19.3 in for size A, 14.8–22.8 in for size B, 15.8–22.8 in for size C). KOKUYO lists 425–495 mm (16.7–19.5 in) for ingCloud. Warranties differ: Herman Miller lists 12 years (3-shift) for Aeron; KOKUYO lists 10 years for the ingCloud structural frame.

Arms and headrest: Aeron offers arm options up to Fully Adjustable Arms and no manufacturer headrest. ingCloud's arms adjust 80 mm in height and pivot inward, and a headrest (70 mm height adjustment) comes only on the w/ Headrest type.

Comfort philosophy differs too. Some owners find the Aeron's seat pan contouring too deep, while owners of the ingCloud describe an "enveloping sensation"; its gliding movement may take time to get used to. This comparison does not rank comfort.

Who should buy which

Consider the Herman Miller Aeron if:

• You want to choose among three frame sizes (A, B or C)

• You want lumbar options such as Adjustable PostureFit SL

• You do not need a manufacturer headrest

• You want to buy from a US manufacturer store with listed prices

Consider the Kokuyo ingCloud if:

• You want a gliding mechanism that moves with you instead of manual recline settings

• You want a frameless mesh back without a lumbar adjustment

• You can try the chair in person before committing

• You can confirm delivery and service outside Japan

Bottom line

Neither chair is a universal winner. Aeron offers three sizes, lumbar options and US store pricing; ingCloud offers a gliding mechanism and a frameless mesh back with few manual controls. Compare the configurations you would actually buy.
