Foam tiles for kids play/gymnastics etc (Bailiff Bridge HD6)

These are blue foam tiles x10, they fit together like a jigsaw. They’re approx 25 inches by 25 inches each so cover quite a large area. We used to use them for our son running around in the living room due to the noisy floorboards (we’re in a 3 storey house so the living room is on middle floor), but I’m sure they’d be great for babies or toddlers crawling/playing when you need a softer surface, or even kids gymnastics practice. They’re super light and don’t take up much space when stacked!
