Amazon listing: SIHOO B300 Pro Ergonomic Office Chair Without Footrest, 4D Lumbar Support | Adjustable Backrest ＆Seat Depth, 6D Flip-Up Armrests, 3D Wide Headrest，Breathable Mesh, 135° Recline, High Back, Black

Searching for best office chair on amazon? This is the page.

The SIHOO B300 Pro Ergonomic Office Chair is a high-back mesh desk chair sold here in its no-footrest version, and promo code 5AUDNVSE cuts 30% off at checkout. SIHOO has a 30% coupon on the chair's page as well; clip it before you check out so you do not miss it.

The headline is how much of it adjusts. A 4D lumbar support moves to line up with your lower back, while the backrest and seat depth both adjust so the chair can be set to your frame. The 6D armrests flip up when you want to slide closer to the desk, and a wide 3D headrest sits at the top of the high back. Breathable mesh covers the chair, and the backrest reclines to 135 degrees for breaks between tasks.

If you have been trying to narrow down the best office chair on amazon for long work-from-home days, this one gives you plenty of fine-tuning without a footrest you may never use. Clip the coupon, enter the SIHOO B300 Pro ergonomic office chair discount code at checkout, and confirm the savings before you pay.

Who should buy it (and who should skip it)

This chair is aimed at remote workers, students and gamers who spend long stretches at a desk and like to dial in every adjustment. The flip-up armrests are handy in tight desk setups, and the high mesh back with headrest suits people who lean back during calls. Skip it if you want a built-in footrest for reclining breaks, or if you prefer a padded cushion back over mesh.

Before you buy the SIHOO B300 Pro Ergonomic Office Chair Without 3D: quick tips

  • Confirm the no-footrest version is selected, since the listing shows three options to choose from.
  • Measure the gap under your desk to make sure the chair slides in with the armrests flipped up.
  • Spend a few minutes setting lumbar height and seat depth after assembly; small changes make a real difference.
  • Keep the assembly instructions handy so you can revisit the headrest and armrest settings later.

SIHOO B300 Pro Ergonomic Office Chair Without 3D coupon & promo code FAQ

Does the SIHOO B300 Pro come with a footrest?

Not this version. The listing is for the B300 Pro without a footrest, which keeps the base simpler. It still includes the 4D lumbar support, adjustable seat depth and backrest, 6D flip-up armrests, 3D headrest and a recline that goes to 135 degrees.

Can the armrests on the B300 Pro flip up?

Yes. The 6D armrests flip up, which lets you slide the chair closer to a desk or under a table when you are done working. They also adjust in several directions so you can set them to match your desk height and arm position.

Does code 5AUDNVSE work with the 30% clip coupon?

Try both. Clip the 30% coupon shown on the listing, then paste 5AUDNVSE into the gift card and promo code box. Look at the totals before placing the order; stacked savings appear as separate lines, and a single line means only one was accepted.

How far does the SIHOO B300 Pro recline?

The backrest reclines up to 135 degrees, so you can lean back for a call or short break and then return upright for typing. The high back and wide 3D headrest give your head and shoulders something to rest against while you are reclined.

Is 5AUDNVSE still working?

It was active when we last checked on Oct 22, 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 B300 Pro Ergonomic Office Chair Without 3D coupon or discount code?

Yes – 5AUDNVSE is the current Amazon promo code (30% off). Amazon calls it a promotion code; it works the same way as a coupon or discount code at checkout, and the listing also has a 30% clip-on coupon.

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.
