I purchased this dog bed, the gugu Sleep, at the end of last year. I haven't used it much, so it's in good condition. I've washed and prepared everything, but it's a little bumpy. However, I think it will flatten out with use. Low-resilience, high-resilience. I'm looking forward to hearing from anyone interested. The retail price was 16,900 yen. Measurements taken when laid flat: 57cm x 43cm
