Small single mattress

Description

I bought this mattress for my son to go back to his room after hip surgery.
I just can't use it as the edges are slightly soft and I can't risk him falling out.
Brand new and not been used once and the reason for not sending it back is because it came suction packed in a little box and I cannot get it back rolled up to return
Iv tried numerous delivery companies to do the return but no one will take it because of the size
I paid £56 but will take £30.
