SPRDENG Ergonomic Office Chair — 4-Way Lumbar, Flip-Up Arms, SGS Gas Lift! $129.99 CAD (46% Off)

SPRDENG's high-back ergonomic chair is down to $129.99 from $239.99 — that's $110 off for a chair that adjusts in ways most budget office chairs don't.
The lumbar support moves four ways: up/down and forward/back. That's rare at this price. The headrest adjusts 5 cm vertically, and the seat slides 10 cm forward or back. Whether you're 5'2" or 6'3", you can dial in a position that actually supports your spine.

The backrest uses dense mesh that's thicker than what you'd find on a typical budget chair, and the seat cushion is filled with high-density foam that won't bottom out after a few months. The armrests flip up 90 degrees, so you can slide the chair under a desk when you're done.
Underneath, you're getting an SGS-certified Class 3 gas lift, a steel 5-star base, and 360° silent-rolling casters. Weight capacity is 300 lbs. The recline locks at 90° for focused work, or you can unlock it to 135° for a quick break.

Rated 4.1 stars across 332 reviews and ranked #11 in Home Office Desk Chairs. Assembly takes about 30 minutes with the included instructions. If you're shopping under $150 CAD for an adjustable, well-built ergonomic chair, this one checks a lot of boxes.
