I was a little nervous about ordering because someone posted a photo of it not fitting on an Arms Reach mattress (I have one). but i decided to trust the good reviews and go for it because those from the company are hard to find and also expensive. Well I love these sheets! They're soft, cute, come in great packaging if you're gifting them and they definitely fit! Now if you would just stretch and let go, yes. it will flex the mattress a bit, but official too. This is because these mattresses are thin enough to keep the baby safe. But if you just take the time to make sure it sits flat and presses against the mattress, it should line up nicely! I've attached an image for proof.
