No. You should never flip a Lull mattress, as they are designed with only one side to be on top. Flipping the mattress and sleeping on the wrong side can result in altered performance and greatly reduce its comfort.
Although not designed to be flipped, rotating Lull mattresses can extend their life by allowing for more even wear. This is especially important if your partner is a drastically different size or if you don’t sleep with a partner at all.
