Boss Design Sia Cloud Knit

The Boss Design Sia Cloud Knit Chair is one of 5 new designs in the Sia range. The Sia has focused its design around sustainability, with just 30% of the structure being produced with virgin materials, with the remaining 70% all recycled materials. Manufactured using less components and without adhesives, the Sia Chair is created with longevity in mind, making it easier to replace parts and recycle components improving the carbon footprint.

Keeping with the theme of nature and light the Sia is available in Black, Copper Brown, Reed Green and Oyster White. Customisable with a choice of 8 colours in a knitted mesh back described 'as a soft cloud texture'. Seaqual Yarn (a 100% post consumer recycled plastic waste collected from land and sea) is woven in to the mesh, adding a cushioning and softness. Opt for the Camira Oceanic fabric a 100% post consumer recycled fabric to decrease the Carbon footprint further.

At Office Furniture Scene, we pride ourselves in supplying top quality, UK manufactured products to our customers & will not supply cheap imported furniture. The vast majority of our products are made to order in a high-tech UK manufacturing facility & our stated lead time for these items is 10-14 working days. Products which have a longer lead time are indicated on the individual item page. Arranged installation of your order may sightly extend this lead time.

Many products available on our site are subject to free delivery. This can be seen by the free delivery icon on the product page. Products without free delivery are subject to delivery costs of 10% of your net order value and are subject to VAT charges. There is a minimum delivery cost of £20.00 & orders with a value in excess of £600 (excluding VAT) qualify for free delivery. Delivery charges are visible in the Checkout process.

Unfortunately, at present, we are only able to deliver within the UK mainland and cannot deliver or install at some remote UK highlands & islands.

To maintain a cost effective service to our customers, we may vary the delivery method based upon your location or order size. Some large, heavy items may need to be delivered separately from your main order due to carrier limitations. We will inform you if this is the case.

Unless your order is being installed by one of our teams, the order will be delivered to a ground floor entrance location.

OFS have been very helpful setting up an order for 5 chairs for our office. They have been of great assistance with regards to sorting out the order and communication has been brilliant.


Ordered a Herman Miller Embody chair with a one-week delivery time, received a phone call after placing the order to confirm delivery for the next day! Chair arrived well packaged, would definitely recommend.


I highly recommend this place for a working from home office chair. Really helpful advice and a chance to see which chair suited me best.
