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.
