Who should buy it (and who should skip it)

The B100 SE is a sensible pick for students, remote workers on a budget and anyone replacing a kitchen chair at the desk. Flip-up arms make it especially handy in tight rooms. If you need a headrest or seat-depth adjustment, which are not mentioned for this model, skip it and look at SIHOO's higher-end chairs that list those features.

Did code SIHOOB100SEP work for you?

Checked by the AmazonHaul Deals Team · last checked Oct 23, 2026

We find codes from sellers, brand promotions and our Facebook groups, open each Amazon listing to confirm the discount, and mark codes as ended when members report them. Product details come from the Amazon listing – we have not tested every product hands-on. About us · How we earn

What is the weight capacity of the SIHOO B100 SE?

The seller lists the B100 SE as supporting users up to 300 lbs. If you are near that limit, look over the base and gas lift details on the listing too, and make sure every assembly bolt is fully tightened before you start using it daily.

Does the SIHOO B100 SE recline?

Yes, it has a three-gear tilt that ranges from 110 to 135 degrees. That lets you sit near upright while typing and lean back further for reading, calls or short breaks. Pick the gear that matches the task and switch as your day changes.

Do the armrests on the B100 SE move?

The armrests flip up, which means you can raise them out of the way when you want to sit closer to the desk, tuck the chair under a table or settle into a more relaxed position. That is handy in small home offices with limited floor space.

Will code SIHOOB100SEP combine with a coupon?

There is nothing to combine it with at the moment, because this listing does not carry a clip coupon. SIHOOB100SEP on its own delivers the 40% discount. Choose your option first, then apply the code at checkout so it attaches to the right version of the chair.

Is SIHOOB100SEP still working?

It was active when we last checked on Oct 23, 2026. Seller codes usually run 24–72 hours or until a set number of uses is gone, so apply it soon. Our team marks a code as ended as soon as members report it.

Is there a SIHOO B100 SE Ergonomic Office Chair coupon or discount code?

Yes – SIHOOB100SEP is the current Amazon promo code (40% off). Amazon calls it a promotion code; it works the same way as a coupon or discount code at checkout.

Do I need Amazon Prime to use it?

No. Promo codes work for any Amazon account unless the promotion box on the product page says Prime-only.

Why didn't the code apply?

Usually a different size or color than the one the code covers, a one-per-account limit, or the code sold out. See all the fixes.
