Organic mattresses promise clean, non-toxic, cool sleep. However, they do usually come at a premium price, which is why holiday sale events like Memorial Day a great time to invest. The good news is that the 'big four' organic mattresses are on sale, including a queen Avocado Green mattress down to $2,039 at Avocado, down from $2,399.The best organic mattresses use natural, high-quality materials like wool, latex, bamboo and cotton. These are all breathable, moisture wicking and temperature regulating, making organic beds fantastic for beating hot summer nights.The extended Memorial Day mattress sales bring down the price of four of the top organic mattresses: Awara, Zenhaven, Avocado and PlushBeds.

Despite the expense of sourcing natural, organic materials, the Awara has managed to keep the Classic well within the mid-range price bracket.When I slept on the Awara Classic for three weeks, I was amazed at how comfortable and supportive it was. I had previously slept on the Birch Luxe Natural mattress, which costs $1,968 for a queen, so I wasn't expecting much from a mattress that's only $799 for a queen.
