Tanning Ledge/baja Shelf Furniture................Ledge lounger?

We are getting a fiberglass pool that has a tanning ledge. I was golfing today and talked with a lady who has Ledge Loungers in her backyard pool.

She was not a big fan as she said they are super heavy and still float? And they are uncomfy and expensive. She was willing to sell me hers

Just curious if anyone has ledge loungers or any furniture they have found for these ledges. we are salt water.
