The Bottom LineNectar and Avocado are poles apart in their feel, construction, and features. Nectar is a memory foam mattress, molding the curves of side and back sleepers for exceptional pressure-relief for back sleepers. On the other hand, if you sleep on your stomach, Avocado provides a balanced comfort and support for a comfy rest. However, some customers complain of feeling stuck on Nectar owing to thick medium level memory foams. Especially, if you are overweight or have a larger build, the China-made Nectar may not be suitable choices for you. Avocado and Saatva are both highly supportive. Avocado is medium-firm while Saatva is available in three different comfort levels, aiming to personalize your sleep experience. Saatva is more cost-effective and offers more value. With the traditional innerspring feel, Saatva also provides the best comfort and support, including specialized lumbar support, best for backache relief and prevention. If the organic cotton is a must, then Avocado is your mattress. In any other case, Saatva seems to offer so much more for the money, making it a great choice here.
