I made the mistake of just using the website, which I understand from their employees, is only for advice only and should not be taken seriously. Sadly I made the foolish assumption that something marked Firm Mattress Foam, and a Branded 'quality product' would be fit for purpose. I am so disappointed with my online order, Frankly sponge cake would have been more resilient! When I called to try and sort this out, I was told that I ordered the wrong product and that they would have recommended a different material had I asked! And told to email my complaint and call back later. Then when calling back, I was summarily told that as I chose to order the foam to fit- I have no come-back ( even though the item was NOT FIT FOR PURPOSE) and could not exchange the goods for a product that would be FIT FOR PURPOSE. Customer services basically would not help me, I am over one hundred and twenty pounds out of pocket and they just don't care. Beware their website, and don't expect the help that these other "reviewers' claim to have received- interestingly over the christmas break when the firm was closed.
