These sheets are soft and I like that they come in a variety of colors, but they slide all over my bed. Its as if the pockets are too deep and even though there is elastic to keep them from sliding off the bed, they don't fit as nicely on my split king as I would like. My mattress is about a 15 inch mattress too, so it is definitely a thick mattress.I recently purchased a Sleep Number Split Head king sized bed. I ordered 2 different sets of sheets and was disappointed in the fit of the bottom sheet but the mattress itself raises separately on each side so I kept my expectations low. After one set tore at the point of movement, I went looking again. I ordered 2 fitted sheets since I now have the top and pillowcases from the others. They are amazing! They stay put, they are soft, just the right thickness and the fit is perfect.Very nice sheets. Quick shipment. Wash very nicely. I would recommend these sheets.The color, the softness, and feeling makes this a perfect fitted sheet! Worth the extra buck!I have been looking for a true white pillow case and I finally found it. Good quality tooI purchased Twin XL fitted sheets for our adjustable beds. Sheets are very soft and feel good. There is some wrinkling if you don't take them out of the dryer quickly. Fit was very good as there is elastic all the way around with elastic strips in each corner that fit under the mattress. Fit snug and wrinkles were not a problem. Stays put and does not pull out from corners. I will purchase again. Highly recommend.These are soft, comfortable, wash well and are exactly what I needed. Much better bargain than purchasing in Dillard's. They've been washed about 10 times; no pilling, and holding up well so far.I got the standard pillow cases to replace some worn cases and they are exactly what I wanted. They fit the pillows and are soft after washing. The sage color perfectly matches my sheets. I'm really happy with them.
