Hi Luca, I used the product with 2 x 27" Samsung monitors (not curved and with a bezel of 1.5cm) and I have to say that they fit but just at the limit. Maybe if you have a very thin bezel it might work but I cannot guarantee.

Hi I settled 2 x 24" monitors and still a lot af space in between, hence It should fit perfectly with 2 curved 27" monitors.
