Question: does this old mattress from the 1950's or 1960's contain asbestos?

2017/09/09 Anonymous asked:

Is a type of use for asbestos in mattresses? I found a patent for fireproofing mattresses that was unlike what may have been used here in the cotton batting.

The mattress is from the 50s or 60s and has only this batting under the fabric cover and above the mossy stuff.

Might it contain asbestos fibers, or was asbestos used mainly in stuffed ticks and as a pad inside the polyurethane models?

I was surprised to see that there was so little involved in the mattress. Just a thin cottonlike outer fabric, then the batting (which I hope is not containing asbestos) and then the brown stuff and springs.

Here's the appearance of the outside if it helps.

It's got plastic handles and vents on the sides. I think it might be a Sealy brand. T - private email to editor

Reply: the mattress shown above and just below probably does not contain asbestos but some mattresses did indeed use that material

Old mattress asbestos content question (C) Inspectapedia.com SZI appreciate both the question and the photo.

The brown fibrous material in your photo does not look like and is very unlikely to be asbestos. That material looks like a natural fiber, probably hemp orJute.

However and perhaps not entirely incidentally, some jute was contaminated with asbestos but typically only where jute bags were used to transport asbestos itself, as we explain at ASBESTOS CLOTH.

Asbestos was however used in some fire-resistant mattress products and also in some heated mattresses, as well as in special electrically-heated mattresses intended for medical applications.

The use of asbestos felts and fabrics is described in patents as well as in asbestos exposure research on the asbestos exposure of workers in asbestos-using mattress shops.

Wild (1921) described a fire resistant mattress design that might combine polyurethane foam, fiberglass, and asbestos fabric. And below we illustrate an asbestos-pad used in the Simon George patent from 1968, granted 1970.

Some heat-tolerant mattress designs used asbestos both for fire resistance and as a means of directing heat to a desired location, such as Clark's patents (1945, 1946) for an electrically-heated mattress intended to treat the human body.

None of the patents I reviewed used loose-fill asbestos in their designs, all used asbestos fabric or an asbestos-felt-like product, and in all cases the asbestos was not the topmost layer of the mattress.

However if a mattress is falling apart, such as the mattress in your photographs, indeed IF an asbestos fabric or felt had been present it might be deteriorated, firiable, and exposed.

You might be able to spot such an asbestos-containing mattress by observing
