US-based online mattress retailer Casper has launched in the UK, giving British customers access to products endorsed by Leonardo DiCaprio, Tobey Maguire, Ashton Kutcher and Adam Levine. Casper is now in its second year of business, having achieved $100 million of sales.

Its UK launch puts it in direct competition with Eve Mattresses, a startup which has been heavily investing in marketing in recent months. "When we started this journey two years ago, we couldn't have imagined just how fed up customers are with the old model and the products available to them," Casper co-founder Constantin Eis said.

"We're proud to respond to the incredible demand we've had from Brits, especially considering the country's challenger attitude towards the traditional retail industry and its role in the European market.

"We're excited about this new chapter and look forward to providing our growing customer base with a phenomenal experience.”
