Real Homes Verdict

This new release from Silentnight’s Eco Comfort range is reassuringly chunky, and while the heavily buttoned top looks lumpy, once you’re horizontal the undulating surface doesn’t register. It kept us both cool and comfortable and we slept well. The eco-factor is very impressive, too.

This new release from Silentnight’s Eco Comfort range is reassuringly chunky, and while the heavily buttoned top looks worryingly lumpy, once you’re horizontal the undulating surface doesn’t register. Witchcraft? 

So, I’ve been reading a lot about how to achieve the best night’s sleep (and been scared half to death about the medical dangers of failing in this quest). There’s loads of great advice out there and they all start with the fairly obvious revelation that if you’re uncomfortable you constantly move around and are basically working out when you should be sparko. The best way to prevent this maniacal thrashing revolves around pressure and surface area, aka support. The more of your body that is in contact with the mattress, the less the shoulders and hips (or lower spine if you’re a back baby) have to take the strain. 

I am telling you all this now because it was the first thing I noticed when I laid down on the Mirapocket 2000). There’s no memory foam topper or latex layer but, regardless, my body did sink ever so slightly into the mattress. My entire length was in contact with the surface (except my neck of course) – could I have found sleeping gold? 

I was feeling pretty positive when I turned off the bedside light, and Nick (my husband) wasn’t moaning either, so an all-round good start. I started on my side and all was well, then moved on to my back and that was comfortable too. I tried sleeping on my front but it was a no-go. I’m really baffled how anyone with even the teeniest of breasts can manage to find comfort that way. Moving swiftly on, the next morning arrived all too quickly, which is always a great sign. In short, neither of us really recalled waking and we both got out without the need to oil our joints with WD40. S’all good.     

This is the latest mattress in Silentnight’s award-winning Eco Comfort range. As you might guess, the ‘Breathe’ addendum refers to several new sweat avoidance features. If you read the online bumpf, it all sounds very impressive (if slightly OTT on the science; we’re not curing cancer here people) and I am delighted to report it works. I’ve just slid past 40 and, while I’m not quite at the hot flush stage, sweaty sleeping is suddenly a real issue. Not so on this mattress, I was coolness personified all night.

To check out the motion transfer situation, to overcome the fact I didn’t notice Nick moving all night due to being virtually comatose, we did a bit of role play. Bear with me. I got Nick to thrash about a bit to mimic his usual style when he isn’t sleeping well/has drunk too much caffeine. As with most pocket spring mattresses, I did feel him moving more than with a memory foam but not enough, I can only guess, to stir me if I was sleeping soundly. The girls had a brilliant time bouncing on it though, with Kitty (seven) almost touching the bedroom ceiling when she really put her back (or rather knees) into it.

There’s also a soft and medium option in the Eco Comfort Breathe 2000 range but we opted for firm, which is aimed at those who sleep both on their sides and backs. Unsurprisingly then, the mattress does feel pretty firm. Our extremely kind and ever-patient firmness testers (three male, three female, ranging from 10 to 17 stone) rated it between seven and nine (see graph above), so only just one spot from ‘hard as nails’. Nick and I found it firm enough but there was still enough comfort to feel like you were sleeping in a bed not the bath. After a bit of debate, we agreed 7.5 to 8 was a fair assessment (though of course Nick learnt to choose his battles long ago).

Happily, our firmness verdict was supported by the weight test (above). It measured a lowly 5cm on the edge, and just above 7cm in the middle.

Returning to the matter of posture, you can see from Nick’s beautiful black-spotted back (below) that he was supported pretty evenly, with his spine only rising at pillow height, which is to be expected. There is a very slight lumbar spine sag (did I mention I’ve been nerding up on this stuff?), which suggests his shoulders and hips are not sinking in enough but it wasn’t significant enough to cause any pain.

How does the Mirapocket mattress rate online?

This is a new launch so there are no reviews online as yet. However, the first Eco Comfort mattress, which has the same recycled bottle top layers, is rated 9.1 out of 10 on Reevoo (160 reviews), which is pretty promising.

What do you get for your money?

Silentnight’s five-year warranty is less generous than others – the standard is closer to a decade. And after one year, they charge a usage fee, which increases year-by-year as a percentage of the retail price. Basically you won’t get a completely free replacement if your mattress is found defective after one year. On the plus side, this mattress is extremely well priced for the quality on offer so your initial outlay will be less. Oh, and as mentioned already, you can exchange your mattress after 60 days if you’re not happy.

Is the Mirapocket mattress worth it?

It’s a yes from me (and Nick). It’s a bit Ronseal – does everything it says it will. What more can you ask for? It kept us both cool and comfortable and we slept well. The eco-factor is also very impressive and, in the current anti-plastic climate, feels even more important. Apparently Silentnight has already prevented 105m plastic bottles from winding up in landfill or the sea, and presumably the addition of this new model will see the stats soar. This mattress alone repurposes 150 plastic bottles in the making. If you do buy one, you’ll have one more reason to sleep soundly through the night.

Ever wondered what it’s like to sleep on recycled plastic bottles? Me neither, but the answer is 'surprisingly good'. The Eco Comfort and Eco Breathe layers are made from recyclable plastic bottles and fibres that are breathable and 'channel moisture away from your body to prevent overheating through the night'. Best not to dwell on where that moisture goes… There is also a Breathable Coolmax surface layer, which again is focused on cooling and moisture control. Under this triple layered technology lie 2,000 pocket springs, corralled to provide extra support at the hips and shoulders. As all the soft stuff is on the top, it’s a no-flip number but you should rotate it regularly for longevity.
