A spare clean single mattress (Astley Bridge BL1)

I’ve had the same old matress for a few years that is knackered and has a few stains on it and my dad can’t afford a new one at the moment despite mine being ruined. If anyone has a spare one lying around by any chance, that would be much appreciated, as it would be really nice to sleep on a clean, comfortable mattress for a change. Thankyou for your consideration 💗
