Because Avocado mattress are made using natural and organic materials (which are hardy too), expect the experience to be firmer, heavier and more solid than your average all-foam model. As we have said many times there’s no deep pressure relieving memory foam sink. Online Avocado customer reviews are mixed, some customers liked the lumbar support offered by the zoned innerspring base unit and credit this for their improved sleep quality. Others found the mattresses too hard and firm and complained of exacerbated aches and pains. Avocado Green and Avocado Vegan are both Firm mattresses (or Medium Firm, once you add the topper), and like any new mattress will take a little time wear in.
