The Bottom LineBoth Casper Wave and Dreamcloud are medium-firm and offered in only one comfort level. Casper Wave with its zoned support is rated well for back support. However, this 11.5-inch Casper is considered unsuitable for heavier sleepers. Although China-made Dreamcloud is 15-inch thick, some stomach and back sleepers report stress on joints due to excessive sinkage. The Nest Hybrid Latex is hybrid in construction and available in three comfort levels, soft, medium, and firm. As a result, you can select the Nest model best suited for your sleep needs. The 13-inch Nest Hybrid Latex is a better choice than Casper and Dreamcloud in terms of comfort and support. The cushioning layers are responsive and equally comfy for all body structures and sleep position preferences. Dreamcloud with microcoils and Casper Wave with ventilated foams keep sleep temperature comfortable. Being hybrid, Brooklyn Bedding Nest is again a clear winner as it sleeps the coolest of these three mattresses.
