Mattress storage bag and mattress cover

[Amarillo]

We have a four fold Brandrup mattress for our Beach.

When travelling and camping we often have it folded in half, and it can be used as a fixed child's bed in the rear.





What I hope to do is have a cover made for the mattress, with the cover also able to be used as a storage bag for the fully folded mattress.



This net is what I have come up with for the design of the bag/cover.



Dimensions of the mattress are:
Folded in half: 147 x 100 x 15 cm
Folded in quarters: 147 x 50 x 30 cm

Material colours to match our seat covers.

Any thoughts before I submit to @Jackyards for a quote?
