I'm so glad Wayfair gives you 100 days to try out their mattresses, because this one seemed good at first (I'm a side sleeper), but after 90 days I have these conclusions: For me, this mattress ended up being too soft. I've been waking up hurting for the past few weeks, and with my arm and hand numb. Also, it sleeps quite hot. I decided to return the mattress after I had secured another elsewhere, and the Wayfair return process was extremely easy! So thankful not to have it be a hassle. Thanks, Wayfair!
