The Bottom LineEndy and Casper Wave are both foam mattresses. Brooklyn Bedding Aurora is a luxury hybrid mattress. The Endy with its medium firmness is rated good by back and some stomach sleepers. Casper Wave is available only in a medium-firm comfort level while Brooklyn Aurora is available in three comfort levels, soft, medium, and firm. Casper Wave and Endy have similar features but differ in quality, and therefore, in price. Endy is ranked best for budget and offers basic features and quality. The only discerning feature of the Casper Wave is its targeted zoned support that helps achieving proper spinal alignment. Otherwise, the mattress offers standard mattress features for a pretty high price tag. Brooklyn Aurora costs less than the Casper and offers a better value for the money. You can choose the firmness to suit your sleep preferences the best. Being a 13-inch hybrid, the Aurora is remarkably supportive for heavier persons. The cushioning, responsive foams make it an equally comfortable choice for lightweight persons. The US-made Aurora is clearly the best model in this comparison.
