Most Comfortable blanket!
Color: White, Size: Queen(90"*90")
Silky smooth and soft. The smooth side is cooler and good for summer nights while the patterned side provides a little more warmth for cold nights. Have not needed anything else. Works great for me - hot sleeper in Florida with AC at 73 and ceiling fan on. Might have to kick a leg out in the middle of the night or find part of the blanket that is not heated from my body and then I can stay cool. If the AC is turned down just one degree to 72, I stay cool throughout the whole night and sometimes cold. Blanket would probably be too warm at any household temperatures above 74 unless it was FL winter or a colder climate. Nevertheless, it is so comfortable on the skin and easy to move around in.

The softest summer blanket ever!
I bought this wonderful & underestimated king size blanket on Amazon from SnuggleSac. I got it because of the reviews & the company was rated very well. It came faster than I thought. I got the arctic blue color & it is beautiful. I have a queen size bed but love oversized blankets. I’m so happy I did. I have really bad neuropathy in my hands & especially my feet from an allergic life threatening reaction to the flu shot. If I forget my meds, have a busy day my feet & or with my hands-which I have been, they are on fire with shards of glass feeling. I get sweaty (dang hot flashes) easily too so I have to be really careful on how soft a blanket is. It is summer in Ga & the only blanket so far that did not cause so much excruciating pain was my heavy winter cuddle duds that I got from kohls that they don’t carry anymore, it is way too way to hot for summer also & just sheets no matter how soft they are like rubbing sandpaper on my feet. This blanket is THE softest I have ever felt, that was lightweight but heavier than a sheet or two sewn together, is very cool to the touch, didn’t cause me pain from having it on-even on bad days, there was no smell, the quality is so far top notch-only used it for 3 days now & what I was worried was the reverse side being harder or too rough to reverse it but was so happy both sides are equally soft. Both my daughter (who wanted to take it) & my husband want both one now. My dog has his own pillows that he always slept on my bed & now he sleeps on the blanket. Even he loves it! I just pray it holds up for a long time to come & I will update if there is any change! Definitely recommend this blanket! Love it! Thank you so much SnuggleSac
