So long as your mattress is in a fit state and meets all of the requirements, you will be able to donate your old mattress to a non-profit organisation or local charity. This is an option many people forget about since they assume that because their mattress may not be working for them, it could still be of value to someone else.
There are numerous different charities that accept furniture, however, we recommend enquiring with them first since the things they accept may vary depending on demand and space. We recommend considering charities such as the British Heart Foundation, Furniture Donation Network, Emmaus or the British Red Cross, to name a few.
However, just like other means of free disposal, there are a few advantages and disadvantages of donating your mattress to charity.
