I used Shadow foam because I like to try and use the best on anything on the market however after using the 1st couple of sheets from a pack of 5 I found the rest to be covered in bubbles and unusable which was really disappointing. After being told by Shadow foam to “turn them up side down and use them” (which means it would have been red instead of black) not what I paid for or the look I wanted. All I wanted to do was return those sheets and get a refund on the 3 sheets I’ve now put in the bin (I wasn’t that impressed by the product so I didn’t want a replacement). They gave me a 30% refund and basically said we’ve done everything we can which left me disappointed with the product and their customer service, I definitely won’t be using or recommending again which is a shame.
