Worth knowing: The warranty is Officecom’s one-year guarantee service, which covers products showing the one-year warranty icon on the product page; check before you buy. The recline angles are not given on the product page.

Only here	★★★★★	The lowest seat of the eight at 41.5 cm, and the only one its seller recommends for heights of about 150–165 cm (two points)

Know before you buy

Seat height decides the fit before anything else. The five go from 41.5 cm at the lowest (Officecom RESTIVA-02, which its seller recommends for heights of about 150–165 cm) to 54 cm at the highest (Officecom YS-1).
Lumbar support is not all alike. Only the SIHOO M57 moves both up and down (5 cm) and in and out (4 cm); the Itoki Salida YL7R moves 40 mm up and down, and COFO publishes no adjustment range for the Chair Lite.
Published recline angles run from 126° to 128°. The Itoki YL7R locks at four positions — 102°, 111°, 120° and 128° — while the two Officecom chairs lock at three but give no angles.
Warranties differ in kind, not only in length: three years on the whole chair (SIHOO from purchase, COFO from delivery), by part for Itoki (three years on the structure, two on mechanisms and moving parts, one on the surface finish), and a one-year seller’s service for Officecom.
All five arrive for you to assemble, and weigh about 16.5 to 20.5 kg. COFO says its Chair Lite takes about 30 minutes.
Footprints vary by 10 cm: the SIHOO M57 is 61 × 64 cm, the RESTIVA-02 68 × 67 cm and the COFO Chair Lite 71 × 71 cm.

Easy to live with20 pts
- Set by the recline, starting at three stars. Add one if the back locks at four or more angles, and one if a maximum of 125° or more is published; subtract one if no angle figures are published (five at most, one at least).
Trust15 pts
- Set by the warranty: three years on the whole chair four stars, one to three years by part three, one year two. Add one if the top 30 Rakuten listings for the model number carry 100 or more reviews averaging 4.4 or higher; subtract one if fewer than 50 (five at most, one at least).

What we dropped

Candidate	Verdict	Why
Itoki Salida YL8	Runner-up (68/100)	68 points, above two of the five, but ¥46,990 earns only one star for value, and the Itoki Salida YL7R fills the same lean-back role for ¥25,492 with a deeper 128° recline.
FlexiSpot C5 office chair	Runner-up (67/100)	67 points. It fills the same standard-build, value role as the SIHOO M57, which costs ¥10,000 less (¥23,980 against ¥33,980), also carries a three-year warranty and adjusts its lumbar support two ways; the C5 reclines only to 116°.
AIMchair (AIMWIZ)	Runner-up (49/100)	49 points, the lowest of the eight. At ¥49,800 it is the most expensive, its warranty is one year from purchase, and the product page gives neither recline positions nor angles.
SIHOO M18	Outside the theme	Lumbar support moving 5 cm up and down and 4 cm in and out, a back locking from 108° to 128° and a three-year warranty, but the lowest Rakuten price is ¥19,980, under ¥20,000 (condition 1).
Kokuyo Entry 2 (CCR-ET2)	Held back	A seat height of 40.5–52.5 cm (a 12 cm range), 45 mm of lumbar adjustment and rocking that locks in three positions (0°, 10° and 17°) come close to every condition, but the Rakuten product pages we checked give no warranty period (condition 5).
Itoki Salida CM chair (YCM)	Outside the theme	Flip-up arms set it apart, but the lumbar support is fixed and no locking angles for the back are listed (condition 3).
Itoki Salida YL9 / YL9A / YL9G	Outside the theme	Designed to follow the lower back through the shape of the backrest; no lumbar support separate from the backrest is listed (condition 2).
Itoki Salida YL6, YM4 and One Tone (YNE), and Bonito	Outside the theme	No lumbar support in the specifications on the Rakuten product pages (condition 2). The YM4’s rocking cannot be locked either.
Okamura Nome / CG-M	Outside the theme	No lumbar support in the specifications on the Rakuten product pages (condition 2). The CG-M rocks through 10°.
Sanwa Direct 150-SNC097	Outside the theme	Lumbar support and a seat height of 42.5–52.5 cm, but the warranty is six months from purchase (condition 5). The load rating is 80 kg.
COFO Chair Pro 2 / Chair Premium 2	Outside the theme	Priced from ¥69,999 and from ¥99,999 on COFO’s own site, above ¥50,000 (condition 1).
SIHOO B100PRO, B300pro, B100SE and M102C	Outside the theme	Fewer than 30 Rakuten reviews: B100PRO 29, B300pro 11, B100SE 5, M102C 0 (condition 6).
Uchida Yoko Eniza, Epo, Crene and Carissa 2	Outside the theme	Three Rakuten reviews or fewer each (condition 6).
FlexiSpot OC3 / Officecom GR-002	Outside the theme	Rakuten reviews: one for the OC3, seven for the GR-002 (condition 6).

Questions visitors ask

Which one should I pick if I can’t decide?

The SIHOO M57. Its total across the five criteria was 96 out of 100, the highest of the five.

Which is the cheapest, and how current are the prices?

The SIHOO M57, at about ¥23,980 on Rakuten. The Itoki Salida YL7R is next at about ¥25,492; the Officecom YS-1 is ¥22,990 without arms or headrest, but ¥28,990 in the version we scored. Prices are typical selling prices including tax, checked on the makers’ sites and Rakuten Ichiba on 25 October 2026. They move with campaigns and stock, so check the link before you buy.

Where can I buy one?

All five are sold on Rakuten Ichiba, which ships within Japan, and the links above go straight to the listings — several of them the makers’ or sellers’ own stores, such as the Itoki online shop, COFO’s official store and Officecom. All five arrive for you to assemble at home.

Which suits a short or a tall person?

The lowest seat is the Officecom RESTIVA-02, at 41.5–47.5 cm; its seller recommends it for heights of about 150–165 cm. The highest is the Officecom YS-1, at 44–54 cm. The Itoki Salida YL7R is 43–53 cm, the SIHOO M57 43.5–53.5 cm and the COFO Chair Lite 45–53 cm.

Which has the longest warranty?

The SIHOO M57 and the COFO Chair Lite carry three years on the whole chair (COFO’s runs from the delivery date). The Itoki Salida YL7R’s warranty runs by part: three years on structural parts, two on mechanisms and moving parts, one on the surface finish. The Officecom YS-1 and RESTIVA-02 come with Officecom’s one-year guarantee service.

Which reclines furthest?

On published figures, the Itoki Salida YL7R at 128°, locking at 102°, 111°, 120° and 128°. Next are the COFO Chair Lite at up to 127° and the SIHOO M57 at up to 126° in three steps. The Officecom YS-1 and RESTIVA-02 lock in three positions, but their angles are not given on the product pages.

Which lumbar support moves in and out as well as up and down?

Of the five, only the SIHOO M57’s, which adjusts 5 cm up and down and 4 cm in and out. The Itoki Salida YL7R’s moves 40 mm up and down in five steps, and the Officecom YS-1 and RESTIVA-02 have adjustable positions. The COFO Chair Lite has lumbar support, but no adjustment range is published.

Do I have to assemble it?

Yes — all five arrive for you to put together. COFO says the Chair Lite takes about 30 minutes. The Itoki Salida YL7R and the Officecom YS-1 come with a hex key, and the SIHOO M57 with assembly tools.
