The Gables Care Home, on Highfield Road, received £630 from the wholesale cash and carry business, based on Concorde Way, Preston Farm Industrial Estate.
Two of the firm’s warehouse operatives, Carol Bell and Alison Rafrafi, organised a tombola and raffle to raise the funds.
They persuaded fellow staff and sales reps to donate prizes and customers who visited the warehouse bought tickets.
Dave McLean, manager at Batleys Cleveland, said: “I’m very proud of my team. Everyone contributed prizes to the tombola and raised a great amount of money.
“We’ve all been touched by a family member who had Alzheimer’s and we wanted the money to go to a local organisation that specialises in looking after people with dementia.”
The Gables Care Home has a dedicated facility, called Oak Unit, which provides specialist nursing care for those with dementia.
Kate Charlton, home manager, said: “We were blown away by the kindness and generosity of the staff members at Batleys and can’t thank them enough for donating the money to The Gables.
“We are planning on to use the funds to purchase specialist activities equipment designed to help our residents who are living with dementia, such as dementia therapy dolls.”
