The Bottom LineAmerisleep AS3 might seem to offer the lowest price of all the three mattress models, but due to promotional offers from Loom And Leaf, they are usually priced about the same. Amerisleep AS3 has a medium feel while Casper Wave is medium-firm. The Amerisleep AS3 sleeps cooler than Casper Wave, but Loom And Leaf ranks the best for hot sleepers. Loom & Leaf has both Gel memory foam and organic cover for superior heat distribution. Casper Wave is good for backache relief but ranked extremely low on value for money and customer satisfaction, but Amerisleep AS3 is better for couples due to its excellent motion isolation and edge support. Wave, AS3, and L&L, all are considered luxury mattresses of varying thickness. Wave and AS3 are suitable only for average and lightweight persons. Loom and Leaf being 12-inch thick accommodates all body structures well. Moreover, contrary to AS3 and Wave, you can choose the firmness of L&L, medium or firm, to suit your sleep needs. Hence, whether you sleep on your back, sides, or stomach, you can find the most suitable L&L firmness for you. Of all the three brands, Loom and Leaf ranked the highest in terms of sleeping cool, value for money, and owner satisfaction.
