Thick and firm Nitori's memory foam cushions Set of 4. Size: Width 40cm x Depth 40cm. Height (thickness) is 5-5.5cm. These memory foam cushions are blue and come with high-quality, beautiful covers. The original price of the cushions was about 1300 yen each, and the covers were about 4500 yen, so the total value of the items is about 9,700 yen. I have only used them a few times a year when guests visited, so they have been used very little and are in good condition. Washing memory foam cushions with water is not recommended because they take a long time to dry, but I have hand-washed and dried them. Thank you.
