I did a ton of research on different sites trying to find a lay flat sun lounger, that was light weight and stackable. After reading the reviews I decided to go with this set and I’m so glad I did. They were fairly easy to assemble, but I would recommend using a ratchet Allen wrench instead of the one provided. They are light enough so they are easy to move, but heavy enough to not blow away if it’s windy. They feel well made and you can’t feel the bars when you lay on them (I’m only 120lbs but my partner is 200lbs.) they lay perfectly flat for sunbathing on your stomach, and sit up enough so you don’t have to hold your head up to look straight ahead. They also allow airflow underneath so you stay cool. At this price point they were the perfect find!
