Writing this review as a warning to others. I bought a therapur 3600 mattress from Dreams in April. I had saved up for a decent mattress and was over the moon with it. Last week I leaned the mattress up against the wall in my room to hoover and clean under the bed for approx 1 hour and when I put it back down on my bed it appears that the gel in the topper had moved and formed a large hard lump. I waited for it to settle but it didn’t so I called dreams and they told me they were sending a repair man to have a look. When the man got here he spent up to 5 minutes in my house the only thing he said it’s not a manufacturer fault. I then asked was he not going to try and repair it and he said no he can’t as it’s all stitched up. Rather confused as that’s what I thought he was sent to do I let him go. Dreams did not contact me i had to contact them and they told me point blank they will do nothing about it, it’s not their issue apparently and as I had stood the bed on its side for “a significant amount of time” it’s my fault. Is an hour to clean the bed a significant amount of time? Should I expect this to happen? What if I moved house how am I expected to move the mattress without putting it on its side? Not to mention it was delivered to me on its side. There was no warning when I bought this product that it can not be put on its side or I would never have bought it. I am so gutted that a big business like this would treat a customer this way I hope my review stops this happening to anyone else
