You’d probably want to be able to sit down after blowing this much money.

Four ancient chairs have sparked an unexpected bidding war, selling for a staggering $1.4 million at auction — even though they have no seats, backs or upholstery.

The 300-year-old decorated frames, made in 1778 for the younger brother of ill-fated French king Louis XVI, were expected to sell for around $350,000, French auctioneers Artcurial predicted.

But the two armchairs and two regular chairs ended up selling for four times that amount after an unexpected bidding war, the auction house said.

Artcurial did not reveal who bought the damaged furniture, which have changed hands several times and were sold by a Swiss collector.

Even the highest estimates put the sale at no more than $550,00 — decidedly less than half the ultimate price in the auction last month in Paris.

They were made by master craftsman Georges Jacob and scupltor Jean-Baptiste-Simon Rode for Charles Philippe, the Count of Artois who became Charles X, for his bedroom at his Château de Bagatelle.

The decorations were befitting of a count who “was one of the most influential and whimsical figures of the reign in terms of taste,” the listing said.

They were eventually confiscated during the French Revolution, which led to the beheading of his brother, who was married to Marie Antoinette.

The chairs are “one of the most daring examples of the creativity and excellence of the craftsmen at the royal court’s service,” the auction house said, praising the “rare inventiveness and originality.”

Despite being just the frames, the historical furniture is in a “remarkable state of preservation,” Artcurial said.
