Play Mats & Activity Gyms for twins

One big mat, not two small ones. Twins share floor time from the start, and a single generous play gym with two babies under it is the actual picture of month three. Buying two standard mats mostly buys you a storage problem and a living room with no visible floor.

Used is the obvious call: mats and gyms are fabric and plastic arches that get outgrown in months, and the washing machine resets them. Check that the arch toys are intact and nothing is recalled, then spend the savings on the floor-time upgrade that matters with twins, which is a mat big enough that they cannot reach each other's faces.
