Review on 🛏️ Authentic Japanese Floor Futon Mattress Cover: FULI 100% Cotton, Queen Size, Gray - Made in Japan by Krystal Simmons

The instructions clearly state to dry flat but I washed lukewarm and tumble dried on medium and the Shikibuton is a queen size, also Ful Stilli, and fits in perfectly. It was a bit tight at first, the edges of the shikibuton were bent right after washing, but after sleeping there were no problems with it, and the whole set lay flat. (I also have a regular queen size mattress topper on the Shikibuton so the extra layer and sheet still fit neatly over everything.) I will experiment with subsequent washes/drys to see if the sheet continues to shrink . The sheet itself is made from comfortably crisp cotton, and the full Shiki cover allows the entire set to be folded away after use. Considering that typical decent queen size bedding sets usually cost over $100, that's a pretty good price for the 100% cotton quality and comfortable design.
