If you are a person who sleepssideways,you'll want a sleeping surface with a lot of ‘pressure relief’. It refers to the ability to disperse while supporting your body weight as well as conforming to your shape.A mattress with cushy memory foam or a fluffy topper tends to have the maximum pressure relief. Hence, you should always test out mattresses by lying down to get a real feel. Furthermore, mattresses from Sunday come with 100 nights trial, so you can test it before buying it! Great deal, isn’t itIJ
