I love these sheets! They are crisp yet soft against the skin. We have a 10" memory foam mattress that we use them on and there is more than enough space for a thicker mattress. We do have a problem with them sliding up from the corners though from time to time. It could because it is not a tight fit on our mattress, but it isn't a huge problem. It seems to happen more so a couple of days after a lot of activity on the sheets, so a quick pull and tuck while making the bed the next morning and the sheets won't ride up.The past few nights have been cold here where I live and I usually need an extra blanket thrown between my duvet and sheet set but these seem to be enough. The weave seems to be tight enough to not let any air slip through. That with my down alternative duvet cover and I sleep comfortably all night long. No chills from being too cold and no pools of sweat from sleeping too hot.Shortly after buying them my daughter got into my makeup and she decided wiping her hands on my sheets would be a great place to clean herself up. After changing my bedding I took everything to the washer and as I was doing so my daughter snuck back into the room to finish "cleaning up" and again she wiped her hands on my sheets after touching the foundation she had spread all over the floor. So once again I changed the sheets and noticed the makeup she wiped on my sheets this time had actually seeped through the sheets onto my mattress protector, something that had not happened with our MALOUF FINE LINENS. The sheets I had on the bed came out of a bed in bag. I knew they were not great sheets to start with and could tell they were thin sheets, nowhere near the quality that MALOUF offers, but they were the only other sheets we had for our bed since we had just upgraded the size of our mattress.Needless to say, we will definitely be buying more linens from MALOUF.
