Sometimes in life, you have a problem that you have been meaning to do something about but just haven’t. For me, that issue was my mattress. We have had our current mattress for a few years now and it’s recently started to become problematic for me. It is a spring mattress with a memory foam topper and it now has some dips and sags in it where we lie. I guess the problem with these mattresses is that you can only turn them, not flip them. This hasn’t bothered my husband so much but I have been waking up with pain in my neck and back as a result.

Introducing The N:rem Sleep System

A few weeks ago an email pinged into my inbox from the lovely Elise at N:rem sleep system asking if I would like to try out their comfort changing tablets*. During the trial, you are sent 5 foam tablets to try. After checking out the product I jumped at the chance to try it as the concept really appealed to me.


The N:rem Sleep System Is Designed To Help Chronic Pain

The N:rem sleep system is unique. It is designed in such a way that you are able to tailor it so that it offers you the support that you need. It is composed of 5 different reflex foam tablets– two super soft, one soft, one medium and one firm– that you can arrange on your bed to suit your individual needs. I love this concept!

As someone who suffers from fibromyalgia, I find that my pain changes not only in severity but also location. When I get bad pain in my hips, for example, my current mattress can suddenly feel too firm and unforgiving and getting to sleep can be difficult as a result.


The N:rem Sleep System Is Fully Customisable

You can arrange the comfort tablets in any order that you like and you can adjust them at any time if you need to. Each tablet is 12cm thick and the N:rem comfort changing mattress topper comes in varying sizes from single right up to super-king. With the larger sizes, each side of the bed can be made up differently (there are 5 tablets for each side). There are some suggested

There are some suggested setups on the website to help get you started and if you need any help with setting up there is telephone support available too. I simply played around with them until I found what I liked. It didn’t take me long at all to figure this out. I went for super soft > medium > soft > super soft > firm during my trial.

How I Found The N:rem Sleep System

Immediately the comfort tablets made my bed feel amazingly comfortable. I really liked them from the second I lay on them– they felt super supportive. Admittedly, it took me a couple of nights to get used to them and my sleep was a little disruptive, to begin with. This didn’t surprise me though as I’ve always been like this with any new mattress or bed. However, even after one night, I noticed a difference in my pain. I didn’t wake up with a sore neck or back the next morning and I felt so much better than I usually do. I was impressed.


In addition to them being new and different, I think the fact that the comfort tablets are quite warm was the main factor contributing to my first couple of nights of disruptive sleep. This wasn’t helped by the fact that summer decided to arrive in Scotland for a few days during my trial… not that it stuck around for long mind you! I expressed this concern when enquiring about purchasing the comfort topper and was made aware that the actual mattress comfort topper comes with a coolmax cover to help regulate temperature. During the trial, you are simply given the tablets themselves to try. I have to say, the coolmax cover sounded good to me.

The only other negative of the trial is that the foam tablets moved around a little, particularly off the side of the bed. This wouldn’t have been helped by the fact I usually move around a lot. I go from sleeping on both sides, to my front and even sometimes wake up on my back. Sometimes I think to myself it is no wonder I wake up tired! However, this issue is confined to the trial tablets themselves and it is not reflective of how the mattress topper is. I’ll explain more in a minute when I talk about the actual mattress topper itself. I just wanted to mention this in case anyone else finds the same during their trial and it puts them off.

I Decided To Purchase The N:rem Sleep System Topper

I knew after the first few days of my trial that I wanted to purchase the N:rem comfort changing mattress topper. I had my husband try it out for a night too, as obviously he would have to like it and thankfully he did. That night actually made my mind up for me as I realised the positive difference the comfort tablets had made to my sleep when I had to go without them. Without them, I invariably woke up the next morning in pain. I had initially told my husband to try the tablets for a couple of nights but he ended up only having them for one as I wanted them back after that!

N:REM adjustable mattress for chronic pain sufferers

What further sealed the deal for me was the night my right hip pain flared up. It’s been a while since I’ve had a flare-up of this pain and you have to believe me when I say it is excruciating. I literally cannot walk when this happens. The only thing I can compare it to (from experience) is the pain feels like you have been literally been kicked full force by a horse. I was in agony and fully expected a sleepless night because of this. However, having the soft tablet under my hips was so helpful. I actually managed to sleep that night and to me, that was nothing short of amazing!

I placed my order so that I would receive my mattress comfort topper on the same day that my trial was going back– I did not want to be without it and I think that says it all.


Receiving My N:rem Sleep System Comfort Changing Topper

The comfort changing topper comes rolled up and you need to allow it time to air and settle. The tablets also have a strong smell to them so make sure you do this in a well-ventilated room. The smell dissapates after a few hours. This was the same for the trial tablets and I aired them for a while before putting them on my bed too. In case you are wondering why the mattress topper looks larger than the bed in the photos, this is the bed in my spare room– it’s a double bed and my actual bed is king-size.

My Impressions of the Mattress Topper

The N:rem sleep system comfort changing mattress topper comes with a base layer of reflex foam, which is ridged, and the tablets slide onto this. The whole thing is then zipped up into the coolmax cover. This essentially stops the issue I had with the tablets moving around, which happened to me during the trial (which is why I said it is really a non-issue above).

The coolmax cover is soft, quilted and quite thick. My only gripe with it is the zip on the cover– it’s quite tricky to unzip it and zip it up so that you can move your tablets around as required. I needed help with this and if you have any issues with your hands, such as arthritis, you might find this part difficult. I changed the order of my tablets up a little differently to how I had them during the trial. I went for super soft> medium> super soft> soft> firm– moving the second super soft tablet so that it is under my hips.

How The N:rem Sleep System Has Impacted My Sleep

With the coolmax cover, mattress protector and sheet on top of the foam tablets I can honestly say heat has not been an issue. In fact, the first night I had the comfort changing mattress topper, I had the best sleep I have had in ages! This product is amazing and I love it! I will let my fitbit do the talking:


I can honestly say this has been a brilliant investment. The comfort tablets are great and I enjoyed trialling them but the actual mattress topper itself is even more amazing. If you have issues sleeping because of your pain I would highly recommend trying this. N:rem actually do a complete mattress with this system but, as I am sure you can imagine, it is pricey.

Purchasing A Mattress Topper

The comfort changing topper is a great alternative if you are on a budget. It costs £199 for a single, £299 for a double, £299 for a king-size and £399 for super king-size. If that seems out of your reach, don’t fret. N:rem offer finance that works out as costing £1 a night. You can find out more information about that on their website.

If you are interesting in trialling the product before buying, as I did, you can trial the comfort tablets for 7 nights at the cost of £7 (at the time of writing). If you aren’t satisfied with the trial, N:rem will refund the cost so there is really nothing to lose.

What are your thoughts? Is this something you would try or have you found any other solutions to help you sleep better?

Disclaimer: I was sent the N:rem comfort trial to try for two weeks free of charge to trial in exchange for an honest and unbiased review. However, I then purchased the king-size N:rem comfort changing mattress myself. I received no payment for this post. All opinions are 100% my own.

Update: Please note, since writing this post the mattress topper is no longer available and N:rem are only selling mattresses
