A playmat assembly comprises a sidewall projecting upwardly. The sidewall has a panel or panels of non-rigid material. Separate hoops are connected to the panel, the hoops being made of a semi-rigid resilient material. The hoops cross each other over at least four times to bias the at least one panel into an upstanding tubular-like enclosure in a popped-up state. The sidewall is deformable from the popped-up state to a collapsed state in which the hoops are twisted away from the upstanding tubular-like enclosure. |
