This table has really made a hugh difference in my free motion quilting.  The height of the insert for the sewing machine is adjustable and just absolutely perfect.  So now my sewing machine sets level with the table and no more drag on my quilts.
since I purchased the table I upgradef to a computerized brother Pc400 sewing machine;  which is a lot heavier and broader and ot fits like a glove no problem.  Still loving this sturdy sewing machine table!
