I just LOVE the bedding set! It's even more beautiful than I expected. I got nice accent pillows, wonderful pillow shams and a lovely duvet in a coastal design. I even bought a large size area rug and curtains to match the bedding in the blue and beige colors. It's absolutely stunning. Thank you so much Quahog Bay.

The extra stitching and re-enforced area at split allow the sheets to not rip at the point where all other sheets I have owned rip or tear.

These sheets are the best. The feel is luxurious. These bamboo sheets were discontinued for a while so very happy they’ve come back. I have a California king split top with a 4 inch topper and have no problem with these sheets fitting.
These flannel sheets are exceptional.
The split king sheets are incredibly soft, warm, and cozy, perfect for the recent Southern cold snaps. Unlike our old sheets that have pilled and slipped, the Cinch Fit design system secures these perfectly to our split king adjustable mattresses. Even with a minor order shipping hiccup, their customer service (Beth) was fantastic and resolved the issue immediately. **Five stars for quality and exemplary support.**
