Single Bed Base (St Albans AL4 (Marshalswick))

We are urgently looking for a single bed base (only), long story short it is for our adult son who has autism and lives in supported living, he has broken his current bed base (by constantly jumping on it). We have a tough bed on order but it can't be delivered until late October so we are looking for an interim solution to allow him to be comfortable at night and hoping somebody may be able to help him. Thanks in advance for any answers.
