Some of the things they sell on their site are dodgy and woucher takes no responsibility for this...

Yes they are! "Quilted memory 3000 Pocket spring double mattress"…
We purchased a "Quilted memory 3000 pocket spring matress where we paid £134 plus £20 for delivery. After having slept on it the first night, places where our bodies laid have sunk! Total disappointment! Our old mattress is in a better condition than this one! I am disgusted that first time ever I bought something from wowcher proved to be totally useless!
