True Sleeper Premium Low Resilience Mattress Single Size Thickness: 5cm x Width: 97cm x Length: 195cm I purchased this last April, but it didn't suit my body, so I stopped using it after 5 days. After that, I compressed it and stored it in the closet. I used it with the beige dedicated cover and another cover on top, so it wasn't used directly against the skin. Before listing, I took it out of the compression bag, dried it in the shade, and washed the covers again. There is no sagging in the sponge, but there is some slight yellowing on the edges, so I have marked it as "Slightly damaged or dirty." The instruction manual states that due to the nature of the True Sleeper material, it will gradually yellow due to ultraviolet rays and nitrogen compounds in the air, but this does not affect its functionality, so please use it with confidence. When packing, I used a new blanket, but due to the structure of the mattress, it is a material that easily attracts hair. I have removed as much as possible, but please purchase only if you can understand this. Please note that it will be shipped compressed with the cover attached. - Brand: True Sleeper - Color: Beige - Material: Polyester - Size: Single Size Thank you for viewing.
