Genuine BMW 7 Series (G11) comfort seat professionally converted into a luxury office chair by R3VISION. Finished in brown Nappa leather with black armrest pads, offered at a reduced price due to honest wear: seat padding 10/10 with no sagging, leather 7/10 with worn-through reflective piping and creasing from use, trims 9/10. The 7 Series is BMW's flagship, and its multi-contour comfort seat was engineered for all-day support: adjustable backrest width, extendable thigh support, four-way electric lumbar and soft Nappa cushioning that adapts to a wide range of body shapes. The chair retains almost every electric adjustment from the car - seatback recline, seat tilt, thigh support extension, backrest width, upper backrest angle and four-way lumbar - powered by an on-board battery with charge gauge, so no trailing cables. It adds a robust office-grade mechanism: gas cylinder height adjustment, smooth 360-degree rotation and height-adjustable armrests with sliding, lockable pads. Designed, assembled and tested in the UK and made to last decades rather than years. Width 70 cm, height to seat cushion approx. 48 cm, weight approx. 40 kg. Includes 1-year warranty, 30-day returns and free UK mainland delivery. An independent aftermarket conversion by R3VISION LTD, not affiliated with or endorsed by BMW.
