What a brilliant idea, Emily! I like that you've put together gymnastics mat and a bed, it makes so much sense! Also great to give you something else you could do instead of lying down in your bedroom. It would make being grounded a lot of fun....What would you practice on your gymbed? Rolly-pollies? Cartwheels? I'd love to use this for handstands... I wonder what else you are going to invent next!
