"We had a memory foam mattress that needed replacing a so we decided on this igel mattress as it claimed to disperse the heat more effectively, we had to wait for 4 weeks for it to be delivered but having tried it for 2 nights this mattress is significantly cooler than our previous memory foam mattress, it is a firmer rating which I will have to adjust to, but it is fine. I suffer from severe pain and insomnia so I was rather concerned about trying a new mattes but I did manage a little more sleep than normal over the last couple of nights, so I am hopeful! The chemical smell was strong for the first night, but by the second night it had faded. The one thing we didn't realise was how much deeper this mattress is compared to our old one, so we will have to buy new sheets and I struggled to get into bed as I am small!, so on the whole we are pleased with our purchase, just wish I could have afforded the matching bed frame to go with the mattress. Spending a lot of money on a mattress is a consideration for us all but we spend a lot of time sleeping (if we are lucky) so it is money well spent."
