THE key to a good night’s sleep is the right bed ... and Huntingdon manufacturer Staples has made a king-size bed fit for the Queen.

To mark 60 years since Queen Elizabeth II's Coronation, Her Majesty is opening Buckingham Palace's gardens to more than 200 royal suppliers for a Coronation Festival to celebrate the best products the country has to offer.

And among those with a royal invitation is Staples, part of the Myer's group, in St Peter's Road, which has produced the creme de la creme of the sleeping world, a one-off £10,000 work of slumber art called the Ambrose.

Sarah Calvert, head of sales, said: "We were invited and decided to take part because it gave us the opportunity to show off the best of our craftsmanship."

The unique masterpiece, named after Staples founder Sir Ambrose Heal, took more than 400 hours for highly-skilled craftsmen to construct.

The padded upholstery bases are layered with coppered four-inch conical and pocket springs, each separated by an insulating layer of wool, and there are antique-finished wooden legs and a brass signature plaque.

The mattress is crafted with the same attention to detail. It is hand-sewn and contains 4,500 pocket springs - the whole bed has 6,000 springs compared to the most popular Myer's mattress that has 800.

The springs are topped with latex and 'hand-teased' horse hair which allows for ventilation and breathability. Next is a layer of merino and lambs' wool as well as Bactrian camel hair and, to top the mattress, the bedmakers have used alpaca fleece, known for its soft and luxurious feel.

The mattress is encased in a hand-stitched Belgian damask fabric and has an embroided signature.

Marketing manager Kasia Czura said: "When we started to design the bed, about January or February, we decided we wanted to use the finest materials to make the best bed. The theme of the show is innovation and tradition so we incorporated that into our design. We have a modern-style bed made in a traditional way.

"We will look to build more of the Ambrose but only if we get 60 orders to mark the 60 years since the Coronation," Mrs Calvert said.

Staples' royal story started almost 100 years ago when King George V had an accident on his horse in France in 1915 and his doctor prescribed a Staples mattress because of its spinal support.

The company has kept its Royal Warrant since 1932. In the last decade, the firm has supplied the royals with about 50 beds, including one for the Queen's corgis.

Mrs Calvert said the warrant was beneficial to the whole of the company, which was taken over by Steinhoff
