This Rotherham business says it is the largest independent mattress retailer in the UK. Chief executive Steve Adams co-founded the company from his bedroom in 2003 and created one of the first online retailers to offer a next-day delivery service. In 2021, Mattress Online processed 128,500 orders and doubled sales to £37.4m. It also unveiled plans to acquire and open ten physical stores within five years. In March 2022, the company bought The Skipton Bed & Sofa Centre for an undisclosed sum.
