1912 Company established by Edward Thompson Morriss. The Marmet Pram Co was a manufacturer of high-quality prams for babies. Marmet prams, or baby carriages, were useful for several generations. The prams offered convenience and comfort to the parents, especially when they travelled with their babies.
Marmet produced a wide range of prams for babies. Marmet twin baby prams were specially designed for parents blessed with twins or children with less age gap. The old wooden prams of the 1920s and 1930s are still much sought after for their vintage value.
Marmet baby prams were also offered in such materials as chrome, iron and steel which were strong and durable for extensive use. These prams often came with rain covers to protect the child from rain, wind and other adverse conditions.
Marmet also offered high-end pram models such as the Marmet Imperial Coach-built Pram which were designed for those with luxurious tastes. The pram featured chrome body and elegant wheels that facilitated smooth movements. The back rest of the prams provided ergonomic comfort to the baby seated inside.
