This is a Panasonic bathtub step. It provides support when stepping over the bathtub. It's mainly recommended for those who use it as a step. - Model Number: PN-11820BR - Brand: Panasonic - Color: Mocha Brown - Features: Non-slip processing - Usage: Improving safety during bathing - Weight: 2.4kg - Retail Price: ¥24,200 Thank you for viewing. The seat height can be easily adjusted to 5 levels: 12, 14, 16, 18, and 20cm by simply moving the pin (see image 6. The right side in the front is 20cm high, and the left is 12cm. I only changed the height of one leg for viewing purposes, and of course, all four legs can be adjusted to the same height). It has non-slip processing (each leg has 3 suction cups, for a total of 12 suction cups), so you can use it with peace of mind. The top panel is also made of a non-slip material. It is also mold-resistant, so you can use it hygienically for a long time. It provides support when stepping over the bathtub for those with weak legs and back, the elderly, etc. My relative used it, and it was a reliable product and very good! I think it was used about 10 times, but I can confidently say that it is in a clean condition without any noticeable scratches or stains! There are no instructions. There are no smokers or pets in the household. Immediate purchase is welcome! I will take waterproof measures and ship it. I am committed to honest transactions. I am a beginner on Mercari, so it may take some time to ship. I will do my best to ship within 7 days at the latest, so thank you for your understanding.
