3 washes and rough as a cob.
Size: King, Color: Teal, Size: King, Color: Teal
Got these about 2 months ago, the feel soft enough and fit well, think stretchy T shirt material, but after three washes they have pilled all over and become very rough. Just as bad as the two year old set I replaced with these. Will not purchase again.

Good for between seasons
Size: Twin, Color: Blush
Very nice jersey sheet set! The color is perfect and it washed well. The weather is too warm for flannel, but too cold for our regular knitted sheets. These sheets are thin but warm. The perfect “between seasons” weight to keep my toddler cozy at night. We’ll see how they hold up over time but so far so good. Very happy with my purchase!

Soft, Breathable Sheets That Feel Great to Sleep On
Size: Twin, Color: White
This Amazon Basics jersey sheet set was a really good purchase. The cotton material is soft, stretchy, and breathable — it feels like sleeping in a comfortable T‑shirt. The fitted sheet has a nice snug fit that stays in place, and the flat sheet is lightweight without feeling flimsy.
The fabric washes well, doesn’t pill, and stays soft after multiple loads. It’s a great everyday sheet set for anyone who likes that cozy, relaxed jersey feel. Overall, comfortable, easy to care for, and great value for the price.

The Perfect Sheets To Lie On While Writing Amazon Reviews
Size: Full, Color: Light Gray
As I write this, I am laying on an adjustable full sized bed by Hofish and a 10.5" comfort foam mattress by Classic Brands. I know I sound like I am an Amazon plant, but I swear I am not. I'm not even a stockholder anymore.
This is the most awesome bed stylings combination I have had in many, many years. In fact, it is the best I have ever owned and it is beat only by some ritzy resort I stayed at on vacation like 20 years ago, though I admit I was pretty drunk the entire time so my memory might not be the most accurate.
But getting back to today... these sheets are great. I washed them twice - I'm not a neat freak, I am just amazingly disorganized and easily distracted while doing laundry, so tonight they went though two wash cycles and one dry. And then I put them on the bed. While these sheets are not deep pocket sheets, they don't need to be with this mattress. There is enough room and border for them to tuck and wrap with the elastic to give a strong grip under the mattress, which is important as the adjustable frame continually put the sheets and mattress though its repeated adjustable calesthenics-type positioning. The other two sheet sets I have used since I got this bed have struggled poorly with this. In the day or so and at least a dozen position changes, these sheets stay in place with no popped corners to exposing the bowl as the head and feet rise. Of course, till will tell if it lasts, but so far they are the best of the batch of sheets in my closet.
As for texture, they are awesome. I'm a dude. I don't really know what thread count or knit or whatever really means. But these sheets feel like a well-washed favorite, quality rock & roll concert t-shirt. And not one of these glitter puff stupid new groups, like a real rock band from the 80s that now charges $250 for a concert ticket and $60 for a t-shirt...but that group you saw back then, paid $10 for the shirt and you STILL have it and love to wear it because it is perfectly molded to your body, soft and reliable. The kind of shirt you will wear under your suit at work and just grin not just for mental middle finger to corporate dress codes, but because the t-shirt is just that great of a feeling.
Well, that is what these sheets feel like. And now you get to sleep in it. It is that awesome.
In LA right now we are having a nasty heat wave, but these sheets don't seem to bake me even with my stuttering AC. The flannel sheets I love seem to trigger the butt sweats as soon as I lay down in this heat, but no such problem with these.
So really, I'm absolutely happy with these things. I am going to order more in other colors as soon as Amazon gets them back in stock. Great price, great quality, great comfort, great fit, great deal. It is that simple.

Soft smooth and wrinkle free!
Size: King, Color: White
The most comfortable sheets I’ve had in years! Soft and don’t wrinkle up in the bed. Some reviews said they are thin but I think they’re perfect! I don’t want super thick sheets as we are hot sleepers. These are the perfect feel. They also stretch very well to fit on my mattress all the way around and I have a thick mattress! My precious sheets were a struggle to get over the corners but these fit perfectly. Would buy 10 times over! Such a good value as well!
