Not permanent press.
Size: Queen (90" X 90"), Color: 02 - Hotel Double Embroidery
Very nice looking but not permanent press. I guess I should have known that since it's 100% cotton. Beautiful cover looks messy.

Great option for 100% cotton
Size: Queen (90" X 90"), Color: 11 - Bright White (No Comforter)
really love the look and feel of this duvet cover set. I had another duvet cover from bedsure that was polyester, but wanted to switch to 100% cotton. Bedsure is always spot on with quality. It is slightly rough but cotton gets softer the more it’s washed. I was debating between the bright white and natural white shades, and was worried that the bright white would pull too cool toned in my room but i’m so happy I chose it cause it looks so nice. The cover has high quality ties on the inside to attach to duvet cover and the zipper is also very durable. No loose strings or pilling. The fabric is cooling and lightweight. I read so many reviews before making purchases and was debating between this set or one that was more high end, and i’m happy I went with this option

Great quality
Size: King (104" X 90"), Color: 21 - Pastel Blue (No Comforter)
I absolutely love this comforter set. The material is incredibly soft and comfortable, and it makes the bed feel so cozy and inviting. It’s lightweight enough to stay comfortable at night but still warm and fluffy. The quality exceeded my expectations, especially for the price, and it looks beautiful in the room. It also washed really well without losing its softness or shape. Definitely one of the best bedding purchases I’ve made.
