super comfortable, not waking up as often as before
Color: Grey, Size: Queen
decided to try these after seeing the tons of good reviews and since they were on sale. also one of my favorite colors in general which is a great neutral shade for bedding, not too bright and not too dull. I ordered a queen thinking my mattress might have been a queen as I previously bought some mainstays walmart sheets. with that brand the fitted sheet in full was way too small. turns out my mattress is in fact a full it is just that mainstays is not good quality or sized right, so this brand the queen is a bit big for my mattress but not too big of a deal. i am not looking for a perfect look, just covering the mattress is the most important.
anyway since getting these sheets in the mail and giving them a run through the wash and dry before putting them on my bed my sleep quality has improved. the sheets are not too hot, are soft and I actually do not wake up as often as before. the sheets are not too thin like other brands and are not thick like flannel either. they are a nice in between. I wonder if they will help keep me cool in the summer, probably since they are actually breathable. I would definitely reccommend giving these sheets a try, worth the money and a good deal on sale. better quality that other store bought sheets.

Very comfortable sleeping
Color: Spa Blue, Size: Full
I love this sheet set…my favorite color and makes the bed look so cool and inviting. These sheets are deep pocket with additional material so they’re long enough to tuck under the mattress with no problem. The material is soft and doesn’t bunch up like some other brands. The two pillow cases are large enough that my overstuffed neck pillows fit perfectly. I give these sheets a 5 star rating because that’s the highest praise I can give. I might add that the color is consistent throughout the entire set, not streaked or a shade off anywhere!. Very comfortable for sleeping!

Soft sheets
Color: Grey, Size: King
I recently purchased the Utopia sheets and overall I’m very happy with them. The material is soft, lightweight, and comfortable to sleep on. They fit my mattress well and stayed in place throughout the night without slipping off the corners. I also liked that they came out of the wash looking nice with minimal wrinkling. Very pleased with purchase and will buy again.
