It is possible to find early X base versions (not DSG) of these with the original first edition feet, called the ‘domes of silence’. Finding original, usable excellent condition removable covers is very rare. They too were available with a removable hopsack cover by Alexander Girard and with permanent upholstery too on later models. These more traditional ‘four legged’ variants sold in far higher numbers than the DSR and DSW and were the best seller of plastic side chairs outside of the commercial DSS stacking version. The names DSX and MSX were kept the same even after the change from X to H base. This was then replaced by the H base in 1954 which was technically a better made and more versatile fitment which lasted through the generations of shells in years ahead. The original design of base, made for the Zenith Plastics manufactured DAX arm tops had an X criss-cross pattern on the part that connects to the seat top. The X part of the Eames DSX Side Chair name refers to the original base when it was developed. The DSG (Dining Side Guard) which was developed later in the mid-1950s was essentially a DSX with longer back legs that ingeniously prevented the shell from making impact with a wall! The MSX is the same only the M refers to it being medium height. Part of the Eames plastic fiberglass series, the Eames DSX Chair abbreviation stood for Dining (D) Side Chair (S) on X Base.
