Has anyone found a set of front rubber floor mats that fit up to the "buttons" on the floor?
I bought a set of MBB OEM mats but the holes don't match up with the floor "buttons" and consequently the front mats won't stay in place (slide around). Have tried to velcro them down to the buttons but haven't found an adhesive to hold.

 

Are you talking about the all weather mats? I bought a 2017 cls 550 in October and had them throw in a set of the rubber all weather mats. They fit perfectly and snap right in to the floor tabs. You should measure the distance between tabs with another cls to see if they are set different in your car. My floor tabs are about 14 1/2 inches apart, center to center and so are the snaps on the floor mats. If your measurements differ then one or the other is off.

 

the mats I have are too long--the buttons are 14" or so apart but are 5-6" forward of the holes built into the mats
Bought these from
some online place which claimed they fit--think they are actually for an E class (which means they should fit)
Do you know your model number on the mats?

 

2014 cls550 RWD & 4matic = black used 21268060489G33, new 21268062029G33 see attachment.

 

thanks
I found them at MBpartsonline--they do look like a different shape---so I'll see when they show up
