These are very soft and cool sheets for sleeping. Good quality. We bought them for our camper which has an XL full bed which we bought a foam mattress topper for. They fit nicely and feel great. Would buy again. Definitely recommend these sheets.

Beautiful sheets, very nice quality. They are soft and smooth. However, they are much lighter in color than shown in the photo. They are baby blue. That is why I couldn’t leave five stars. They are great for our travel trailer that we spend close to six months a year in.

These 100% Egyptian Cotton Sheets is a total win for my RV king bed! These sheets are incredibly soft and feel so cool and soft every time I crawl into bed. The deep pockets keep them snug and in place, so I don’t have to worry about them slipping off, even with the RV’s movement. Why They’re Awesome: So Soft: Seriously, these sheets feel amazing. The Egyptian cotton is super soft and comfy, like something you'd find in a nice hotel. Great Fit for RV King: The 15-inch deep pockets fit perfectly on my RV king mattress (72"x 80"), and they stay put all night. Breathable and Cool: They’re perfect for warmer nights in the RV. I don’t overheat, and they keep me cool and comfy. Tough and Long-Lasting: I’ve washed these sheets many times, and they still feel just as soft and haven’t shown any wear. If you want to make your RV bed feel a bit more like home, these sheets are definitely worth it. They’re comfy, durable, and just fit perfectly. Highly recommend!

I have to say, I was skeptical about these sheets. I have a Sleep Number flex top king bed. That means that only the head is split. When we first bought it (for my husband's snoring!) I didn't realize how expensive the authentic Sleep Number sheets would be. I bought several pairs and I honestly wasn't impressed with them. They didn't wear properly, for some reason. So, when I saw these sheets for half the price I thought I'd give them a try. They are WELL WORTH THE MONEY. The elastic bands that secure the fitted sheet to the mattress are sturdier than the Sleep Number sheets. They fit snugly and securely and they don't shift or come up during sleep. The sheets are comfortable and soft and a decent thread count. They feel much more expensive than they were. I highly recommend them!

Color: Lavender Solid
Size: Top Split King :78"x80"+34"split
Included photos. These are supposed to be the lavender color, sort of look a bit more so in the sun than what photos show. Several of the seams have loose threads, or haven't entirely caught the fabric. Which I left lots if loose threads all over everything in the wash and on the floor. The center "v" for the flex head portion is ripped (didn't notice until almost had the sheets on the bed). As well, the flex head portion is odd, they continued the thick elastic band all the way round including the flaps, so it makes it difficult to get between the two flex portions of the mattress. Not sure why they did that, the elastic doesn't serve any purpose there. Washing roughed up the sheets, hoping that a few more will resoften them back. Included photo of dryer vent, has to be the most lent that I've ever seen for sheets, is more like what towels loose. Like the weight of the fabric. Hopefully they will be more breathable than the microfiber ones.

I have a Nemo Quasar camping mattress that previously I was wrapping a twin size sheet around for camping, resulting in lots of wrestling around in the middle of the night to get the wrinkles out from under me. These cot sheets have made tent sleeping way easier by fitting much better over my mattress, allowing for more comfortable sleep. They’re a little on the warm side for mid-summer camps, but still light years better than trying to deal with polyester or other artificial materials on my skin. Once fall temperatures settle in they made for very cozy nights of sleep combined with some blankets! I will happily continue to bring these camping with me for years to come.
