mattress cover advice needed

[soootired]

Hi i just bought a second hand corner cot (looks great) and was just about to buy a new mattress online (this choice was easy as they only come in foam) when it came up with an options box for the cover.
I can have a mesh, pvc, polyester for free or amicor anti dust mite, silver fibre? organic or micro climate for extra £10. I have not looked into this at all so does anyone have any advice. would like to buy it soon as i have found a promo code for 10% off. Any help, which is best?

ps always google search for promo codes before you buy anything never mind how small the web site you are buying from. saved £10
