Designs like pool floats and pool noodles are actually meant to be used in the water. These pool chaise lounge designs will float in the pool and can be used for relaxation. The main difference is that you will still be wet when using pool floats.
Pool chairs are different because they are mean to be used outside the pool and not in the water. Outdoor pool chairs can be placed in the areas around your pool like a deck, grass, or concrete. With pool lounge chairs, you can dry off in the sun but still remain close to the pool for another dip. You can also pair outdoor pool chairs with other accessories like pop up canopies and outdoor lounge chairs with patio umbrellas for shade.
