I just upgraded from a Queen size mattress to a Cal King and needed a new, affordable, and nice duvet cover. This Duvet set really is an amazing deal for the price. The fabric is soft, but sturdy, and the ties within the duvet cover keep my duvet insert 'locked in' very well. I haven't had any problems with my insert shifting. I am extremely happy with my purchase, and would recommend this set to anyone who is looking for a duvet cover that is clean, soft, elegant, and affordable.
