FlexiSpot built its name on standing desks, but it has quietly become one of the most talked-about names in affordable ergonomic seating. The FlexiSpot BS8 Pro is the chair driving much of that conversation: a mid-range ergonomic chair that promises the adjustability of something far pricier. This review answers whether it delivers day to day, where it impresses and where it cuts corners.
FlexiSpot BS8 Pro review at a glance
On Amazon UK the BS8 Pro (September 2026) is listed from £178.49, rated 4.1 stars from 100 ratings and in stock, with other BS8 Pro variants up to around £250 depending on the configuration. That puts it above budget chairs like the IKEA Markus and SIHOO M-series, and well below premium names like Herman Miller and Steelcase. It packs in adjustable lumbar, multi-dimensional armrests, an adjustable headrest and a synchronised recline.

Comfort and ergonomics: the FlexiSpot BS8 Pro’s strongest suit
Adjustability is where the BS8 Pro justifies the extra money over a budget chair. The adjustable lumbar lets you tune the support so it lands where your spine needs it. After a week of fine-tuning we found a setting that kept the lower back comfortable through full eight-hour days, something fixed-lumbar chairs cannot promise for every body type.
The armrests are the other highlight. They move up and down, slide forward and back, swing inward and out and pivot, so your forearms sit exactly where you type without hunching your shoulders. The high mesh back breathes well, the adjustable headrest supports your neck when you lean back, and the synchronised recline encourages the small posture changes that keep you comfortable through the day.
Build quality: where does the money go?
At this price you are paying for adjustability, not premium materials. The BS8 Pro feels solid, with a sturdy five-star base and a gas lift that held its height, but the plastics on the adjustment mechanisms feel mid-range rather than machined. Nothing rattled, sagged or loosened in our testing. Assembly took 30–40 minutes with clear instructions and all tools included.
Living with the BS8 Pro day to day
Budget an hour on day one to dial in lumbar, armrests, seat depth and recline tension. Once set, it largely disappears, which is the highest compliment you can pay an office chair. The seat-depth slide is a small but meaningful touch: shorter users can bring the seat in so the front edge does not press behind the knees, while taller users get full thigh support, which the IKEA Markus lacks.
FlexiSpot BS8 Pro pros and cons
Pros
- Adjustable lumbar that suits a wide range of body types.
- Multi-dimensional armrests, rare at this price.
- Breathable high mesh back with an adjustable headrest.
- Synchronised recline encourages healthy posture changes.
- Seat-depth adjustment for shorter and taller users.
- Strong value: premium-style adjustability at a mid-range price.
Cons
- Adjustment-mechanism plastics feel mid-range.
- Takes time to set up properly.
- Warranty is shorter than IKEA’s 10-year cover; check the listing for the exact term.
- More expensive than basic mesh chairs, so overkill if you want something simple.
FlexiSpot BS8 Pro vs the competition
Against the budget IKEA Markus, the BS8 Pro wins decisively on adjustability. The Markus claws back with its 10-year guarantee and lower price. The closer fight is against the SIHOO Doro C300: both offer strong adjustability for similar money, and the decision often comes down to seat comfort and armrest feel (see our SIHOO Doro C300 vs FlexiSpot BS8 head-to-head). Against premium chairs like the Herman Miller Aeron or Steelcase Leap, it cannot match the materials or the 12-year warranties, but costs a fraction of the price and gets you much of the ergonomic benefit.
Who should buy the FlexiSpot BS8 Pro?
Buy it if you want premium-style adjustability without the premium price, especially if you have struggled to get comfortable in fixed-setup budget chairs. Skip it if you want a simple sit-and-forget chair; the IKEA Markus saves you money and setup time.

Verdict: is the FlexiSpot BS8 Pro the UK’s new ergonomic favourite?
It makes a strong case. The BS8 Pro delivers the adjustable lumbar and multi-dimensional armrests that change how comfortable you are over an eight-hour day, at a price that undercuts almost everything offering the same. For UK home workers who want serious ergonomics without spending four figures, it is one of the best-value chairs you can buy in 2026.
