Albeit expensive, what an absolutely fantastic mattress. We tried a few in the store (Llandudno) and were given loads of different tips, advice, and guidance, but this one really stood it for us in terms of quality, comfort, and price. We bought this alongside a King-sized ottoman and we could not be happier. Having used this mattress for just over two weeks, it's somewhat hard to believe, but we have slept-through the night every single night since we bought it, which isn't common for us! It is ridiculously comfortable, and just gets comfier the longer you lie on it. There is plenty of room to lie in comfort without disturbing the other person, and it doesn't seem to get too hot at night either. Despite the 1-star reviews - which I 100% disagree with - we have tried and tried to replicate the 'rolling over disturbs the other person' claim but it's just not true! The mattress seems to give a perfect balance when rolling over, and when awake or asleep, you can barely feel it. Once you're lying down, you just get comfier and you tend to stay in the same position without gettimg achey or fidgety which is great. I am a side-sleeper, and other half is a front-sleeper, and we adore this mattress. It suits us both perfectly. Our main concerns are that it is quite a tall mattress, so feels quite high off the ground/our bedside table at times (especially with our ottoman bedfeame), and extra deep fitted sheets only just cover the mattress on each side. We also just have a mattress topper, but are considering getting a full mattress cover (i.el wrap around the whole thing) instead, just to protect it that little bit more around the edges.
