My club uses 60 " Lifetime tables so I have found some larger round table tops. Couple options:
Currently we use some I got on
Amazon. They are 2mm thick and have a nice surface and come in sizes from 24" to 63" but one says Texas Hold's Em and the other has the seat numbers backwards. Links are below. The 55" size is $75.

The other option is an outfit called Grip Mats that I found on Etsy. They can make round mats up to 59" and they are 3mm think so a little thicker than most. I recently ordered three 59" custom mats. These ran $153 each. I cannot comment on quality yet as I won't receive them until early April. The link for this provider is below.
