This is the 4th sheet set I've bought. The are 100% cotton, what is a microfiber? It's hot, doesn't breath, so thank you Sam's for having the real deal at affordable prices!

Love these sheets. We've used these for years. Last a long time. Cool and smooth feel. Plenty to tuck under the mattress on all sides. Just wish they had more interesting colors. Baby blue and lavender would be nice.

Love these sheets. Soft and wash great. Love the sewed in corners. Fit my king bed great lots of room to tuck under mattress. Will fit 18 in mattress fine. Bought 2 king. Will buy again in other colors.

I think the sheets are good quality for the price. I like the fitted stretchy end panels on the fitted sheet. I buy them for my paralyzed grandson and they hold up fairly well to a lot of washings. Over time the fabric in certain areas has torn.

Washes up well - no pilling. Generously sized flat sheet and fitted sheet give plenty of room for covering up and accommodating an oversized (deep) mattress.

I've ordered these sheets in the past and they were excellent. No so this time. They are ruff to the feel and slightly yellow. Not bright white. Would not order again.

These sheets are exceptional, especially for the price. They launder well and are very comfortable. I first used these at an Airbnb that I helped maintain and then became a fan for our personal use.

Best sheets that I've ever owned. I will never buy any other sheets than these. They're soft, yet durable. Other sheets I've tired felt like sandpaper when you move around. These are quite the opposite!

I ordered these sheets because some others that I ordered for an Airbnb home I manage were terrible. This was my first experience with members mark sheets and they are amazing! Worth the money!

I am very satisfied with the two sets that I purchased. They are heavier than some that I have, they have a smooth feel to them, and they have plenty of corner pocket room.
