We have a Simba hybrid ultra and have had it for over a year now, with no problems. My wife is about 52kg and 5ft, I'm about 6ft 1 and 82kg. So far no hump or even suggestion of one! I mean, what are you doing with your bed, man? Goodness me!

Simba Hybrid Ultra - very good so far and not insanely expensive. Bought as it’s meant to be one of the best available for side sleepers

I was just about to say this too. We have one and really like it. Think my last payment is next month so assume we're on month 11 and so far so good. I am pretty fanatical about rotating it though, which admittedly is a pain in the arse it's so effing heavy...

We’ve had a Dormeo octa spring for 5 or 6 years now and been really happy with it. We returned a Simba in the free trial period because it just wasn’t great.

Oh man, I totally get the back pain and sleeping hot thing. My old mattress was a nightmare for that. I actually ended up trying a simba sleep hybrid a couple of years ago after hearing good things, and honestly, it made a huge difference for me. The combination of springs and foam really does help with support and keeping cool, and I barely notice my partner moving around anymore, which is a lifesaver.

Honestly, I was in the same boat with the back pain and side sleeping, and after trying a few things, I ended up getting a simba sleep mattress, and for me, it's actually been pretty solid for keeping cool and my back feels way better, lol, no sagging issues yet either.

Also have a Simba, also ended up with a big dip where I slept and a lot of back pain. They need to be rotated frequently which we didn’t realise and now we have a useless mattress that can’t be slept on- for various reasons including being away a lot at the time it went past the guarantee period before the problem came to light. Would not buy a foam mattress again, would only get a traditional pocket spring one.

Simba for me. Had an Emma and hurt my hips but Simba was perfect. Gf has an Emma and wouldn’t swap it for the world!
