      I spent over 600 (800) full price on a mattress from another retailer, awful. Couldnt get comfy on it, couldnt get a proper nights sleep because it was so firm and uncomfortable even though it was advertised at a medium to soft firmness which I sent back after the minimum required nights test, This one I got delivered next day after I bought it for just 229 with free delivery and Ive slept great every single night. Absolute bargain for this price, especially for a king size. Id highly recommend buying from here, free next day delivery and quality products

      Bought for a toddler after older kid had same one for a couple years. Ive still managed to have a go sleeping on it and comfortable for adult as well as kids. Very happy with it. Original one is doing really well 2 years on - even with it being used as a trampoline sometimes!
