Bought the pocket sprung hybrid king size mattress in 2018. It was great, supportive and comfy medium firm which I like. However as per other reviews after the first year start feeling a v small indentation generally around where the heavier part of the body lies (regular rotating seems to help to delay this a bit). I'm only 50kg so am a bit surprised. After 2 years I could feel more dipped even after some regular rotation. And it feels more like medium to soft, I was getting more restless night due to achy back, and I'm relatively lightweight. Upon checking warranty it says dip of no more than an inch is considered to be normal so I didn't bother to do anything. And then it just getting softer and softer over the next two years or so. The only spot I could tolerate now is the middle ridge which is still kinda firm ish. But as soon as I roll onto my side I'll fall into the dip and struggle to roll back out. Not to mention I'd have to kick my partner off. Visually I can see the two area where they dip but still not exceeding an inch which means I can't claim the warranty? It's v soft around those area. So yep. Thought I'd pay more to buy something better and with 10 years warranty which can't really be claimed anyway, should perhaps stick with IKEA mattress and get a good topper instead.
