They say we spend up to a third of our lives in bed, and let’s face it, a lot of us would probably like to spend a bit more time beneath the sheets. The least we can do is make it comfortable for you this summer... We're offering you a double AeroFlow CoolBlue pocket 2000 mattress for £169 or upgrade to king size for just £189, saving you up to 77% off Flamejar's prices (correct as of 9.7.15). Looking for a cooler night’s sleep this summer? Today’s deal can be (literally) cooler than the other side of the pillow! A pocket sprung mattress with a 360° vented border, the AeroFlow is specially designed to allow air to pass freely through the mattress and keep it cooler on warm nights. Plus, it also incorporates CoolBlue – an advanced form of memory foam engineered to combine comfort and support with less of the heat discomfort. Top it off with ultra-fresh anti-microbial protection and a luxurious knitted quilt surface and you’re guaranteed a peaceful night’s slumber! Sizes
