Coffee table, wood (Moston CH2)

Long wood coffee table. 40cm high 37cm wide and 138cm long. It has some scratches on the top which you can see in the photo which could be repaired/improved with a bit of brown wax crayon. It has been strengthened underneath with a random bit of wood which is pretty ugly but can't be seen unless you get under the table - makes it very solid though. Rocks slightly on my wooden floor but will probably be ok on carpet or with a small felt pad under one leg?
