Question about Therm-a-Rest NeoAir Voyager Wide

I also suspect an incorrect size specification. 51 cm should only apply to Therm-a-Rest NeoAir Voyager. Unfortunately, I ordered the wrong mat because the information from Galaxus was misleading. I thought the "wide" one was only 51 cm wide and ordered the normal one. When I unpacked it, I noticed that it was very narrow. Could you please correct this in the description and confirm that the above product is the 63 cm wide version?
