FlexiSpot C7

The C7 is our value pick because it packs the adjustments that actually change back comfort into a chair that lists at an indicative ~£340 and is frequently discounted, a fraction of the Leap or Aeron. FlexiSpot specifies a self-adaptive dynamic lumbar that tracks small shifts in your posture and adjusts automatically (and can be locked to a fixed level), a backrest that reclines and moves with you, breathable mesh and 3D armrests, which is a genuinely well-equipped feature set at this price and unusual for the self-adjusting lumbar alone. Note that the inflatable AirLumbar, forward tilt and 4D armrests belong to the pricier C7 Morpher, not this base model. The trade-off against the premium pair above is in refinement and long-term reputation: the mechanism and materials are not built to the same standard as Steelcase or Herman Miller, and reviewers note the array of controls can be fiddly to set up at first. For most home workers with everyday back ache who cannot justify four figures, though, it gets you the important 80% of the ergonomics for far less; step up to the Leap only if you want the more sophisticated backrest and warranty.
