Eight colleagues from Staffordshire law firm Ansons Law will swap their beds for cardboard boxes on Friday 6 November as part of this year's YMCA Burton Sleepout.
Ansons Law is the headline sponsor of the event, which raises money for the charity's work helping people who are homeless or in crisis.
Sleepout participants will spend the night at Pirelli Stadium or take on the "extreme" option of sleeping in St Modwen's graveyard, which is open to over-18s only.
Paula Senior, fundraising and partnerships manager at YMCA Burton, said:
"We are hugely grateful to Ansons Law for coming on board as headline sponsor of this year's YMCA Burton Sleepout and we are really excited to have members of their team joining us on the night.
"Homelessness can happen to anyone, and every pound raised helps us provide a safe place to call home and the support people need to rebuild their lives."
Among the eight Ansons Law colleagues taking part is Jamie Gill, solicitor and joint head of corporate and commercial, who said:
"A single night out in the cold is a momentary hardship for us, but the money raised helps YMCA Burton provide housing, food and support that can change lives for the better.
"We are proud to support YMCA Burton's work to help people in desperate need. We're encouraging colleagues, clients and local businesses to support us either by taking part, sponsoring a sleeper or making a donation."
Joining Jamie on the night are Ian Meadows, director of dispute resolution and property litigation; Richard Saum, joint head of commercial property; Jason Alcock, head of dispute resolution and employment; director Martin Jackson; solicitors Maisie Watts and Joshua Stokes; and trainee solicitor Charlie Woolman.
YMCA Burton supports more than 12,000 people a year across East Staffordshire. Alongside supported accommodation, its services include family mediation, counselling, an emergency food bank, outreach, chaplaincy and furniture shops.
