My only regret with my purchase, was not making it sooner! Since having a baby this is our BEST investment yet. We find ourselves spending far more time on the floor playing with bub (11 months old). Our baby girl is also inlove with this rug and throws herself onto it, lays down, plays.
If you’re contemplating, just do it! You will not regret.
I will say the dark grey one does look sort of like a navy blue, nonetheless we’re inlove.
