Great sheets!
Color: 01 - Light Grey, Size: Queen
These sheets! I love them. They are so soft and comfortable to sleep on. The quality of my sleep has improved dramatically since I bought these sheets. I tend to sleep hot, yet I stayed at a comfortable temperature all night with these sheets. Our bed takes a 21” fitted sheet pocket, and this is the first fitted sheet that I’ve found that actually covers the corners, with a little extra to spare. I will be ordering these again! The price is great, the fit is great, the colors are great, the comfort is great. What’s left to say, except—they’re great!

Soft, Durable, and Great Value for Money!
Color: 02 - White, Size: Queen, Color: 02 - White, Size: Queen
I was pleasantly surprised by the quality of these Bedsure sheets. They feel lightweight yet durable, offering a soft and cooling touch that’s perfect for warm nights. The deep pockets fit my thick mattress securely without slipping off, which is a big plus. After several washes, there’s been no pilling, and the color stayed bright white without fading or yellowing. For the price, the value for money is excellent — they feel as good as some luxury brands I’ve tried. Overall, a great combination of comfort, durability, and quality. I’ll definitely be buying another set in a different color soon!

Durable, well made, recommend
Color: 01 - Light Grey, Size: Queen
It should be 4.5 stars because these sheets are great but I got the light grey and it was more of a barely not white. I would have liked it to be a bit more true to the color choice. That aside, they have been through 6 washes with minimal to no shrinking (washed on hot and dried as hot as my dryer allows but it’s pretty sensitive so it shuts off as soon as it senses dry. Other machines may vary.) I like how the sheet is labeled with a “top or bottom” tag. I’ve experienced no slipping and so far they show no wear and tear like some similar sheet sets I’ve purchased. I would recommend this at the price. They feel soft and have proven durable. I like to change my bedding style a lot and appreciated the wide selection of colors. Again, this was not true to color (very light grey, almost white, when I’d ordered something visibly much darker in the image but called light grey), but outside of that it was a great set right out of the package.

AMAZING SHEETS!! YOU WILL NOT BE DISAPPOINTED
Color: 01 - Light Grey, Size: Queen, Color: 01 - Light Grey, Size: Queen
I've been having trouble finding sheets that didn't pill constantly. THESE HAVENT. The texture of these is so comfortable and it keeps me nice and cool at night. The straps underneath actually help them stay on the bed with no falling off!! I have a queen size bed and it's just me and I didn't have any problems getting these on to the bed either. They are extremely good quality for the price. The sheets I had before this were juicy couture and they pilled so bad they are garbage after 90 days. I will continue to purchase bedsure sheets from now on!!
