I did much research before selecting Leesa. I used the CNN underscored and NYT Wirecutter which recommend Leesa the Sapira hybrid was recommended for side sleepers. Then I comparison $$ shopped and took the Leesa quiz. There is usually a sale most months, so the price was affordable and it arrived much more quickly than anticipated.
Been sleeping on my Leesa now for 30 days and I love it! My back is much less grumbly.
