A retractable fence system for a pool surround includes an array of ground tubes mounted around the pool. A resiliently upwardly biased substantially hollow post is slidably mounted in each ground tube. A retractable non-resilient flexible fence panel is mounted within each post so that, when the post is fully extended above ground, the fence panel maybe selectively extended laterally from the post, through a vertical slot in the sidewall of the post. The distal end of the fence panel, when extended, releasably mounts to a next adjacent post.
