You will need:

2 skeins of 100 gr. Mint
2 skeins of 100 gr. Natural
2 skeins of 100 gr. Salmon Pink
1 skein of 100 gr. Yellow
4 mm. crochet hook
40 cm. zipper
Pins
Tapestry needle
45×45 cm. cushion filling
You will also need the ETNIC Tapestry Crochet Cushion pattern that you can download in three versions. One of them the version with the complete pattern, another with only one side of the pattern (it has two equal sides) and the third, it is just a quarter of the whole pattern, since it is mirrored up and left.

As soon as you start crocheting you will get familiar with the pattern, so I am convinced that guiding you a little with just the third version of the pattern (the smallest) will be more than enough.
