Not quite 5 stars
My wife and I lived with a top of the range Tempur for 14 years but eventually it had to go and unfortunately we couldn’t afford to replace it, since then we have gone through many mattresses our last a premium silent night hybrid which we never found comfortable and replaced after 8 months with this Nectar mattress, this is not a £4000 Tempur but for the price it is actually somewhat comparable, my back has not hurt since sleeping on it and I had forgotten what no back pain actually felt like, if I had never slept on a Tempur I would have given this mattress 5 stars, the only really noticeable difference is the side support is lacking on the Nectar and if you get to close to the edge it will collapse and roll you out if you’re not careful, once you get used to this it’s not really a problem.
