What we thought

We ditched air mattresses years ago in favour of Self Inflating Mats (SIMs) and haven’t looked back since. Although often regarded as the domain of the backpacker, SIMs have come a long way in the last few years and now incorporate greater depths and components like memory foam for improved insulation and comfort.

SIMs are ideal for use in smaller tents, or when you need to keep what you’re packing down in terms of weight and size, but SIMs are also brilliant for popping on top of camp beds to provide a comfortable mattress that will make a standard camp bed much more comfortable, especially for multi-night camping trips.

The Jack Wolfskin Cozy Rest SIM features two identical valves which you simply twist and pull to open. Air is then sucked in and the mat inflates itself.

I like my mattress to provide as much padding as possible, so I always inflate my SIM as much as I can and the design of the valves makes inflation by mouth easy.

After it inflated, I topped it up a bit, I closed off one of the valves and blew a few times into the other before twisting and pushing down to close the valve, popping it inside my tent and making my bed for the night.

Pros

  • Really good quality
  • Stays firmly inflated with no loss of air
  • I like the idiot-proof valves which make opening and closing them very clear and simple
  • The double valves result in faster self-inflation
  • Good levels of insulation
  • Generous width
  • I slept on my side and didn’t get sore hips like I do with my usual SIM
  • Packs down relatively small compared to our usual Vango single SIMs
  • Good size carry bag, easy to pack back into after use

Cons

  • It’s not the cheapest 7cm SIM by a long stretch

The verdict

Our Rating

Quality 5/5

Practicality 4.5/5

Comfort 4.5/5

Value 4/5

Overall Rating 4.5 out of 5 stars (4.5 / 5)

Due to the 7cm depth (I usually stick to a 10cm SIM or more because of my dodgy joints) I wasn’t convinced the mat would provide me with enough padding, but every time I’ve used it, I’ve been proved wrong.

On one recent camping trip, I spent the first night on the Cozy Rest and on the second night, I swapped back and used my usual SIM so I’d be able to do a direct comfort comparison.

The Cozy Rest is more comfortable than my usual 10cm SIM. This surprised me a lot and wasn’t what I was expecting, so, despite the relatively high price tag in comparison to my usual SIM, it does perform better in terms of comfort.

That’s not what I really expected, but it has shown me that it’s not just about depth when it comes to finding the comfiest sleeping mat, though of course, that does help.

If you’re looking to invest in a good quality SIM that provides very good levels of comfort and insulation, but you’re not too worried about pack size, then the Jack Wolfskin Cozy Rest SIM is well worth considering.
