The Bottom LineNectar, Dreamcloud, and Saatva are different in their design, mattress materials, feel, and features. Nectar is a memory foam mattress with a hugging, somewhat sinking feel, (sometimes problematic for bigger body structures). The medium comfort level and thick memory foam in the 11-inch Nectar molds the curves of side and back sleepers for pressure-relief. The 15-inch Dreamcloud is a medium-firm mattress with several layers of memory foam, latex, and microcoils. Although, it may work for heavier persons, some stomach and back sleepers do report stress on joints due to excessive sinkage. Both Nectar and Dreamcloud offer only one firmness choice, possibly because they are imported.. The US-made Saatva is highly supportive sleep surface, available in three different comfort levels, aiming to personalize your sleep experience. Customers appreciate its traditional innerspring feel, luxury features, and affordable price. Of the three mattress models under consideration, Saatva is ranked better for comfort, support, and cooling. Specialized lumbar support is another plus, deemed best for backache relief and prevention. If you prefer foam mattresses, the China-made Nectar and Dreamcloud are suitable options. In any other case, Saatva seems to offer so much more for the money, making it a great choice here.
