A warning to anyone thinking of using these guys like I did. You get NO WARRANTY. These guys do NOT stand by their products at all. They buy the foam in, cut the foam, beyond that you're on your own!! I ordered some replacement seat cushioning, no issues with measurements, order was made to specs. I followed the order wizard to the letter and purchased the extras to ensure longevity. I ordered a Reflex Superior (medium), Polyfibre wrap with stockinette. First impressions were good and I was pleased with the service... 5 months down the line with average use the cushion has completely lost its firmness and I sink into it at awkward bad for your back angles, the very problem I was trying to resolve with my 10 years + old cushions that gave me 8 years of good service. I tried to get some customer service, not knowing what their process was I went in seeking advice rather than demanding a more suitable cushion. However I quickly realised that unless it was a "manufacturing issue" they didn't want to know and had no intention of helping me. I warned them that I would be posting my experience online to help others avoid my problems, I got no response. I'm also going to be seeking help from trading standards as this seems completely wrong. I hold my hands up, I'm quite bitter about the situation but this is 100% true and I'd recommend you avoid this company at all costs. I've never been treated so poorly by any online retailer. I'll leave you with this, less than 6 months of use and their response unedited: "Unfortunately, this would not be deemed as a manufacturing fault so we would not be able to consider exchanging or returning as per our terms and conditions." - Charlie B
