Try before you buy: stay overnight in John Lewis' fully furnished in-store apartment, where everything is for sale

Department store John Lewis is offering customers the chance to stay overnight at special in-store apartments — where everything is for sale.

The fully fitted out apartments in the Oxford Street, Cambridge and Liverpool branches are being offered via random ballot for shoppers to stay over and test out a range of John Lewis products — including that all-important bed.

Each apartment has a fully furnished bedroom, dining and living room boasting a £3,000 sofa, £2,000 dining table and a £2,800 widescreen plasma television, for guests to curl up in front of.

The Oxford Street branch offers a fitted kitchen (complete with £1,300 coffee machine and wine cooler), a study and an indoor terrace overlooking Cavendish Square.

The latest Autumn Winter products can be found in every cupboard and wardrobe with an expert Residence team on hand to answer any questions.

Only available on Saturdays, those staying over will have private use of the apartment from 6.30pm until 9am the next day, with a Waitrose breakfast basket and newspapers delivered as a wake-up call.

There is also the choice of a 60-minute after hours private shopping time or an access all-areas tour of the department store included in the stay.

London customers can also hire out the the Residence for dinner parties for up to 10 people, catered by a professional chef with cocktails prepared by the Residence's mixologist.

For those unable to book a sleepover or dining experience, the Residence remains open to all throughout shop opening hours.

The venue will also host a series of free customer workshops including how to pick the right duvet, tips on creating mood lighting and advice for hosting the perfect dinner party.
