<p>&#39;Young Sainsbury is a cheeky little sausage with the most wonderful eye for detail. His furniture is extraordinary&#39;, says his client Sir Rod Stewart. </p><p>Meeting in Guy Goodfellow&#39;s Chelsea atelier, this week Carole Annett sits down with the design world&#39;s best-kept secret: Jonathan Sainsbury. Founded in 1918, his eponymous family-run business has a reputation for creating some of the finest furniture in the world, often (though, as he stresses, not always) inspired by classical interiors of the 18th- and 19th-centuries. The key to his success? Quality. As he tells Carole: &#39;I only trade off my quality. I don&#39;t trade off price. I don&#39;t trade off being the quickest in the world. I don&#39;t trade off any of that. I only trade off people saying &quot;If you want the best job then go and see Jonny and he&#39;ll sort it out for you&quot;.&#39;</p>
