Convenient bed patent

I have bought something like this before, and it is convenient for both sides. Let your daughter-in-law have a look and discuss it. Let's talk it over. Don't get emotional because of sex. She must be excited and didn't think so much. This is really inconvenient for you. So multi-functional, but it takes up a lot of sanitary corners. The point is that it is inconvenient to get on and off the bed, and this invention is really strange.
