Avocado mattresses have a top and a bottom — they shouldn't be flipped. So if your mattress doesn't feel quite right — or if it feels especially firm — it's possible that it's simply upside down. Don't worry, it happens! You can always double-check by ensuring the Avocado logo at the head or the foot of the mattress is right side up. If it isn't, flip your bed to the opposite side and you'll feel the award-winning gentle support of Avocado mattresses immediately.
