I bought Geltex 1000 from mattressman, and although the mattress itself is comfortable, it filled the entire room with a chemical/mouldy smell that's been there for weeks. I also noticed when I opened my eyes in the morning, they were itchy and watery - clearly whatever chemicals they use to comply with fire regulations are causing this. Why can't Silentnight air their mattresses before sending off to consumers? I'm more concenred about health impact, and I don't trust the EU REACH regulations either - they are constantly updated, and what is considered non-toxic today, may be reclassified as toxic tomorrow. I wish I bought their Eco range instead now :(
