Gym ball (Marsh LA1)

I'm looking for a pilates/yoga-type exersise/gym ball - the type often used to maintain core strength. Needed new or used (and even slightly squidgy) to join a somatic movement class later this month (January '24), I can collect in Lancaster or near to Lancaster. Maybe you have one cluttering up space in a cupboard, room, shed or garage? I could use it! Many thanks, Annie.
