Nope, not Mannington.
The two most readily available manufacturers for "real linoleum
" are Forbo
. As others have mentioned, "Marmoleum" is Forbo's trade name for their linoleum. A lot of folks used the term linoleum generically for sheet vinyl. I think this is because sheet vinyl replaced linoleum as the "new & improved" flooring in the late 50's when the "plastic revolution" started. It was offered in more vibrant colors and patterns - think the 60's.
Between Forbo & Armstrong's linoleums, they are pretty much the same except, Forbo offers many more colors & patterns. They are also the oldest manufacturer of linoleum - Armstrong company is the new kid on the block when it comes to linoleum.
