Bugaboo donkey 

Replacement foam only.

This will make your bumper bar as good as new. 

Bit of wiggling an pulling to get foam on but takes 5 mins, rip old foam off. 

Apply some washing up liquid inside new foams an they wiggle on, onceon they will stretch into place. 

I have been selling foams for prams for years any question please ask. 

Cheaper option rather than purchasing a whole new bumper bar.
