Posts: 42. Re: blood coming through nose and mouth. I've seen it a couple of times at my job (I am not a nurse, but a nurses aide). It's usually when the person is dying of end stage liver disease and varicose veins develop in the esophagus. These veins end up bursting and that's when you see quite a large amount of blood come out of the nose and mouth.
(picnic table image by Horticulture from Fotolia.com) Standard-size A-frames use five to seven lengths of timber for the table top and two to three lengths for the seats. A standard table top height is about 30 inches while the height of the seat top should be about 16-18 inches. Aploon/iStock/Getty Images. Childrenâs picnic tables are made to a smaller scale than regular A-frame tables. They usually feature four lengths of timber for the table top and two lengths for the seats.
The rule of thumb that can vary a bit but should be considered is the height of the seat should be 12 lower than the table. Most tables and desks are 29 -30 high. Placing chairs at about 16 -18 high. Bar height is 42 making most stools around 30 high. So your benches all seem to fit into that chair category of 16 -18 high. The depth would be a design choice rather than comfort if there is no back on it.
