Review: Comfortable, Supportive and Unbeatable Value. - Like others I was sceptical about the original price and the reduced amount, but as the reviews seemed very favourable, I decided to take a punt, the mattress we had bought previously was supposed to be of good quality but after a year it was clearly not the product it was made out to be, so as you can imagine I was a little unsure , my wife has had a bad back from the previous and had to spend a lot of the evening reading to get off to sleep then woke in the morning in pain, well the mattress arrived quicker than estimated delivery date, cardboard box had seen better days but the mattress was airvac packed with really strong polythene , when I went to pick up the box I was amazed at the weight so before struggling up the stairs I took it out of the box then used the stairs to slide the package still in the polythene. I removed the old mattress and read the instructions before opening the wrapping, I knew what to expect when I opened as the previous mattress was memory foam. It opened like an inflatable life raft and soon took its shape, the instructions advised to leave the mattress for a couple of hours to allow to reshape, this was good info , I think it said twelve hours should see it fully resized, the mattress is a Kingsize and fitted the bed perfectly, the height is as described a full 300mm depth, if you like me were not sure which side is which Summer/ Winter then just remember the winter side is the squares pattern whereas the summer side is a striped or lined effect. It is advised to rotate the mattress every thirty days. Then obviously turn over for Summer or winter to suit your situation but remember to rotate every thirty days. The first night we both laid the mattress you could feel its firmness but it was really comfortable, obviously worrying about the next morning and how my wife slept was playing on my mind , so with much trepidation I asked the question and was told an excellent nights sleep was had . So I have asked again after a week and my wife said that she goes to sleep in minutes now and is so comfortable doesn't want to get out in the mornings. My thought "Job Done". I too have found it to be a supportive and very comfortable mattress, the price is amazing too, very good to have a product that is made and delivered from Europe too rather than the Far East which helps the carbon footprint a little. If you don't like a firm mattress it will possibly not suit everyone , otherwise go get one.
Review: After years in pain and discomfort I can FINALLY sleep well!!! - I rarely review things I buy I guess I’m a bit lazy. I don’t want this to sound like it’s not a genuine review but OH MY DAYS this mattress is AMAZING!!! I spent months on research as over the years as I got tired of spending thousands on mattresses which left me feeling underwhelmed - if only I’d known about this sooner! I’m someone who’s been struggling with back pain from two slipped lower back discs for over ten years. I’ve had mattresses ranging from £250-£3500 from big, small, well known and unknown companies, foam, sprung, orthopaedic you name it ive tried it and this one beats them all! I can’t believe the price and quality/comfort! I would rate this as medium/firm def on the firmer side but the structures of the layered foams make you feel as if you’re sleeping on the softest lovely cloud supporting you in exactly the right ways and places! I would happily pay triple or more for this so I’m gonna grab another one for the spare room that I can use once this one is done before they are gone.

### ⭐ It is not comfortable, and quality is just very poor.
*by P***K on 2 September 2020*

It feels like a cheap mattress, and it is simply uncomfortable. More like an air mattress feel than foam. It is light and slippery, and just falls off the bed. They claim to have a policy of 'Love it or Shove it' but that means you pay for the return, and good luck with that, when you return a mattress (packaging and shipping is difficult and expensive). Quality of mattress is poor. It is not what I expected. I would avoid this mattress and specifically the seller. The only one that got no love and got shoved was me, not the mattress " LOVE IT OR SHOVE IT GUARANTEE: Experience and quality for your peace of mind. At Naturalex, products are subject to 5 quality control processes, each range has been subjected to rigorous testing for appropriate home use. All materials are certified hypoallergenic by OekoTex. However, we give you a 60 day trial to try it out. That, along with a generous 10 Year Warranty from Naturalex, will allow you to rest tonight knowing you are in safe hands." It actually allows you to waste a lot of time, effort and money, knowing you are in expensive hand, uncaring hands.
