Update: I’m very happy with this sheet set! I’m currently only using the fitted sheet as I don’t have a need for the top sheet or pillow cases right now. It hasn’t popped off the mattress at all like the previous cheep sheet I had. Original post: The sheet set arrived today. Haven’t actually tried it yet because I need to wash it first. From I can see, looks great. Once it’s washed and on my bed, and can figure out how to update my review I will do so accordingly. It’s soft like most people have said and the color is nice, though they didn’t have my favorite color purple in a shade I like so I got the ‘fancy blue’ (don’t remember the actual name of the color) because I desperately needed a new sheet of quality.

Very comfy sheets, nice fabric

Size: Full, Color: Oatmeal

I wasn’t expecting such good quality forthis price. They’re very soft, but of fairly thick fabric. I’m sleeping great on them. The pockets are deep enough for an 8” foam mattress plus my 3” topper. Will be getting another set for the second bedroom.

Great Sheets!

Size: Twin, Color: Oatmeal

Super soft, wash up beautifully, seem well made — very happy! It’s very hard to find 100% cotton t-shirt type sheets and these are really lovely.

Weirdly textured

Size: King, Color: Dark Gray

I have bought and loved jersey sheets in the past, that have all been as soft as a well worn cotton t-shirt. These arent soft. They have the stretch of jersey, but not the soft smooth texture that they should have. Even after washing a few times these are one of my least favorite sheets I've ever bought on Amazon.

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.
