Costco had some nice lounge chairs, got one from there for about $150 with an aluminum frame. I also bought a couple off Wayfair.com. I was nervous about ordering and spending so much more net but they were great to deal with and outstanding quality.
We have 2 of the springform loungers, about $25 each. Very comfortable! For towels I was planning to make a tree stand out of pvc but decided I don't want something else taking up room on the deck, so I'm going to install hooks in various places on the house brick. For storage we have 2 Keter 150 gal deck boxes from Sam's. They are fabulous!
