These Bamboo Pillowcases Made Me Realize I Sleep Hot
Color: 07 - Cream, Size: Queen (20" X 30"), Color: 07 - Cream, Size: Queen (20" X 30")
I bought these mostly because I kept hearing people talk about bamboo pillowcases and honestly thought it sounded a little overhyped, but I totally get it now. The first thing I noticed was how cool they felt compared to regular cotton. I tend to get warm when I sleep and flip my pillow a million times during the night looking for the cold side, and these actually stay noticeably cooler longer.
They also feel really soft without having that weird slippery texture some silky pillowcases have. My skin has been less irritated lately and my hair definitely looks less frizzy in the mornings. I have thick hair that tangles easily overnight, and these have helped more than I expected.
Another thing I appreciate is that they’ve washed well so far. I was worried they’d pill or lose softness after a wash cycle, but they still feel smooth and nice. They also just make the bed feel cleaner and more comfortable overall. One of those small upgrades that ends up making a bigger difference than you’d think.

Sheets are good. Greens don't match
Color: 08 - Sage Green, Size: King (20" X 36"), Color: 08 - Sage Green, Size: King (20" X 36")
I purchased the sage green sheets to go along with another Bedsure comforter, then purchased 2 more pillow cases (because i
I like a lot of pillows) and the greens don't exactly match. This doesn't REALLY bother me as I feel like its fine with a little "texture."
Sheets feel nice and light and I love the look of it in my room.

Good buy Pillowcases
Color: 08 - Sage Green, Size: King (20" X 36")
I bought these Bedsure king-size pillowcases from Amazon and overall I’m very happy with them. The first thing I noticed was how incredibly soft and smooth the fabric feels. They almost feel silky, which makes them very comfortable to sleep on. When you lay your head down, the material feels cool and gentle on the skin, which I really like.
I also appreciate the zipper closure. It keeps the pillow securely inside the case and makes everything look neat and tidy on the bed. The zipper is hidden well and doesn’t feel bulky or uncomfortable.
The only small downside is that the pillowcases are so smooth that the pillows can sometimes slide around or even slip off the bed a little. However, that’s really just because the material is so silky.
Overall, I would still recommend these pillowcases. They are soft, comfortable, and feel like a nice upgrade compared to regular pillowcases.
