    • Best deep pocketed sheets!
Color: Emerald Green Size: California King
These are wonderful!!! So easy to put on the bed, and they do NOT come off in the middle of the night!! I’ve been through so many sheets, and these are the winner!! They are super soft! Thick, but breathable! The color is exactly what we wanted! Definitely recommend!

    • PERFECT and so deep !
Color: Dark Grey Size: King
Absolutely LOVE these! I didn’t know I needed a deep pocket sheets or that they were even a thing until I googled it and this came up in the shopping area which then brought me into my Amazon app. They’re super soft and fit perfectly on my bed, and the corners DO NOT ride up the way regular king size sheets do after a night or two of sleeping. The quality is pretty great too, I don’t notice a lot of pilling on the sheets or the pillows. I have noticed that it’s pretty great when it comes to stains as well; I’ve got a brand new baby that has definitely spit up on the sheets multiple times already and I don’t notice any stains after each wash where I don’t do anything fancy aside from just regular detergent and the bedding cycle on my machine. Overall really great and would love to purchase more colours! ... show more

    • Don't Fear The Microfiber, It's Just As Good As Cotton
Color: Navy Size: Queen
I was a little afraid I hadn't invested enough to get acceptable quality when I bought the CozyLux Extra Deep Pocket Sheet Set for slightly more than $25. When they arrived and found the extra deep pockets were a perfect fit for my bed after buying at least two other alleged "deep" pocket sheet sets. The sheets are soft and smooth and I'm able to make up the bed with just a few adjustments and it's back to wrinkle-free. The best part is not wrestling with a sheet that is too small to get under the mattress on all sides of the bed. These are great sheets. Highly recommend. ... show more

    • Definitely worth the purchase
Color: Black Size: King
They fit over my adjustable bed perfectly! I have a queen size so had to go up a size to the king and I have absolutely no problems with the sheets popping off or anything! Would definitely purchase these again! They feel amazing and easy to put on without having anything else to hold it down whenever you’re vibrating the bed or lifting it up! The quality is amazing it definitely gives off the expensive look! ... show more

    • It’s okay.
Color: Dark Grey Size: King
It’s very comfortable to sleep on. The quality is good, but it ripped already unfortunately. It’s not to thick or thin. I’m not one that worries about wrinkles so I don’t know about wrinkle resistance. Appearance is good and didn’t fade the color after washing it once, don’t know about multiple washes.The deep pockets on the fitted sheet are amazing, I hate when the sheet slips off while you laying on it, and this sheet doesn’t do that. ... show more

I love these sheets! Arrived on time. Very good quality. Nice and soft. Good thickness as well. Fits my California king perfectly.

    • Fitted sheet stays on the mattress!!
Color: Dark Grey Size: King
I honestly wasn't expecting a ton from these sheets given the price point but I am truly surprised. The fitted sheet actually stays on the bed! The elastic that goes around the entire bottom is a huge plus because it helps pull everything in and there is extra fabric so the sheet will actually go underneath the mattress rather than just hang onto the side. These sheets are also exceptionally soft and not hot material. We love them so far! Ill definitely be ordering some more in multiple colors ... show more
