This is a mattress for a baby bed. I purchased this at the same time as the HZJMD baby bed mattress to add thickness. I bought it in 2024 and used it for a year, placing it under the mattress. It was very useful because it was difficult to find a mattress that fit the size of the HZJMD bed. I placed the HZJMD mattress on top and a waterproof sheet, so there is no direct soiling. It is slightly larger than the bed frame, so I used it by tucking in the four corners. As a result, there is a slight deformation in the shape of the four corners, but I think it is within a range that is not noticeable when used as a mattress. (See photo 5) The cover is 100% cotton and can be washed using a laundry net. It is a product made in Japan. There are no noticeable scratches or stains, but there is a feeling of use due to it being a used item. I hope you understand this point before purchasing. - Type: Mattress - Color: White - Size: 80 x 50 cm (two-fold type) Thank you for viewing.
