I'll be honest, I've never heard of Nathan Furniture previously, but a tip-off via Twitter took me to its site and specifically, its midcentury-inspired Citadel 21 range.
The company has actually been around since 1916, producing furniture of 'quality and value', which presumably means it isn't the cheapest, but it is built to last. This particular range seems to take inspiration from Scandinavian designs of the 50s and 60s, taking in sideboards, coffee tables, chairs, dining tables, cabinets and shelving, all made of teak and all with stylish curves and angles.
You can see some of it above, or check out over the page to see the round extended dining table. The company's own website doesn't sell it directly, but you can pick it up via the Online Furniture Store. Prices for sideboards hover round the £1,000 mark, with other prices varying but starting from £192.
