Pack of 2 Waterproof Chair Pads - Buy 2 & Save £6

I purchased two of these for my disabled wife's armchair. Apart from not looking as thought they could be waterproof, we are nevertheless using them alternately (while one's in the wash, etc) and keeping our fingers crossed that any small mishaps will protect the chair. They give a better look than our previous idea of using a folded bath towel on the chair. The reason why I have not given a bigger star rating is because these things crease up easily when sat on, which in turn hurts the back of my wife's thighs. I've tried ironing them but the problem remains. Nice idea but we'll only really know if they work as and when we need them to.

I am out walking everyday and take a flask of coffee. This pad sits in my small back pack and protects me from cold or wet benches/ rocks whilst I sip my coffee.
I did spill the whole flask on the pad and it absorbed it all. I after cursing popped it in my bag, no dripping or wetness. I washed it in the washer on return- good as new.
