Sales at John Lewis declined last week as customers enjoyed the hot weather outside rather than hitting the shops.
Sales at the department store chain dropped 7.9% to £57.5m for the week to October 1.
The highlight in the home department was an increase in furniture sales, with strong sales online. Fitted furniture saw an increase of 22% on last year, while dining increased by 8%.
The company's Christmas shop launched online and in shops this week, with customers showing enthusiasm for trees and accessories despite the heat.
Online sales were up 14% on last year.
Director for operational development Lesley Ballantyne said: "It was a tough week for John Lewis due to the Indian summer that arrived on Monday. However, a real highlight of the week was the opening of our Chester at home branch. Despite the baking heat, new customers came out in force and the team at Chester give them an excellent John Lewis welcome."
