I got this sheet set from tryit as a sample to write a review on. These sheets are extremely well-made. They are very sturdy and are made with elastic bands on the fitted sheet so they will not slip off. I have a 15 inch thick bed and it fit perfectly over every corner even had extra room for even thicker mattresses. Sleeping in these sheets are like sleeping in a luxury hotel bed. Go buy them you won't regret it I promise!
