We bought a european size mattress for an old ikea bedframe (as ikea don't sell these any longer nor are they stocked on the high street), which meant a longer than usual delivery time scale, but this was made very clear before ordering. The mattress arrived before the expected date, we had a choice of date & the delivery arrived within the specified slot. The delivery guys were efficient, friendly & helpful. The mattress was exactly as described and we love it!

From cooling memory foam pillows to supportive, cushioning mattress toppers, our range of Coolflex accessories help you discover your best night's sleep.
Whether you're optimising your impressive Coolflex mattress or Coolflex Divan Bed with innovative pillows to match, or breathing new life into your current mattress with a comfortable topper, there's no better choice than a Coolflex sleep accessory.
Ever craved that 'cool side of the pillow' feeling, but no matter how many times you flip and turn it, you're still too hot and clammy? A Coolflex pillow puts a stop to that, offering a constant cooling sensation that helps you get the most refreshing night's sleep possible. The Coolflex® Hybrid ICE Cool Gel Memory Foam Pillow, for example, features integrated cooling gel pads that actively draw excess heat away from your body.
If you're suffering from night sweats and menopause, a cooling pillow or sleep accessory will enhance your quality of sleep, wicking away excess moisture and cooling your core body temperature. By getting you to your optimal sleeping temperature sooner, these Coolflex accessories help your body conserve energy, so you can focus on staying in a deeper, longer sleep and wake up refreshed and energised.
You can discover more about the benefits of cooling bedding in our guide.
