Comforter only fits king sized bed one way, look for the lengthwise seams on the sides.
Size: King/Cali King(102"x90"), Color: Gray
Most comfortable comforter I've ever owned. Can't explain it, it truly feels cool while keeping you warm. We tripled it with the cooling bamboo sheets and a cooling bamboo mattress protector and are sleeping way better. Don't waste hundreds on luxury brands that dont work half as good as these, believe me we tried them and these are way better.

~* obsessed *~
Size: King/Cali King(102"x90"), Color: Gray
i am obsessed with this comforter. super soft and silky, and actually keeps me cool at night! it is thinner than i had thought it was but it is not an issue at all. i did think it was a bit on the small size for king bed but my fiancee and i havent had an issue with that either. another plus is that it is not like all these bulky comforters you have to fight to get into the washer/dryer! VERY easy to wash! i will likely just continue buying these when i eventually need a new one!

The perfect comforter for summer!
Size: King/Cali King(102"x90"), Color: Blue
I read all the comments before I ever buy, which is always helpful, it was very positive. I’m absolutely in love with this comforter! It’s so lightweight, but keeps me cozy at night! I don’t know why I waited so long?! It’s exactly as described 🫶🏻😴💤💤

Great blanket!!
Size: Full/Queen(88"x88"), Color: White
The weight is almost nothing. Soft and silky and warm when you need it. It is slippery, but if you put A duvet cover on it almost no slipage. It is a wonderful summer blanket. Thank you.

slips off bed during the night
Size: Twin/Twin XL(68"x88"), Color: White
I never expected this? It will not stay on bed. Slips off during the night. I am a pretty good sleeper. Do not toss and turn that much. I was amazed that it fell off during the night !!! Did anyone else have this problem?
