Product Customer Reviews

I lost the bag :(
Folds down small
Have brought two inflate easy and deflate is a little harder to get all air so packing back into bag may take some time I just folded flat and stored with ground sheet at 20 stone in weight they seem ok have only just started to use them tried them with ground sheet two air mattress two sleeping bag and winter clothes outside seem ok did get some sleep
Incredibly small when packed away! Takes less than a minute to inflate by blowing into the Correct inflation plug.. thereare two plugs so check which is which before use. Make sure that the DEflation plug is in securely, otherwise you will find it slowly goes soft during the night. How comfortable you like it depends on how much air you blow into it, so you will need to experiment. My first use I made it too hard and bounced around like a trampoline. Removing the deflation plug slightly will allow slow release. Removing it fully causes quicker deflation, instant if you happen to be lying on it. packs up incredibly small to fit into your jacket pocket,
I recently spent a king’s ransom on top of the line camping equipment. Certain items have failed after only 2 trips including my previous expensive inflatable pads. So I replaced with this one thinking it’s not so bad if it’s starts leaking after a couple of trips but I’ve been on a number of them and it’s fantastic. I particularly like the fact it has sticky pads on one side so you can turn over without the mat moving. I had the short size (I’m 5”2) and the mat reached from my head to past my knees. Perfect
Exceptionally compact and light
Packs down small, easy to inflate and is a comfortable addition to my kit
Used one on my run up the West Highland Way in September. Took up less space than my Thermalite and at the price I paid I was not so concerned about being ultra careful with it. Worked well, did the job, kept me off the ground and gave a bit of additional ground clearance which was useful. Would strongly recommend using one for comfort.
The color is pretty good, very light, easy to use. Like this product!
light, comfortable, perfect
The weight is very light. The volume is quite small. Very easy for storage. Also easy for inflating and deflating. I like this product.
Athough the length is shorter than my body, but the weight is very light. Easy to inflate and deflate. Very suitable for travelling.
Very quick and easy to inflate. I prefer fully inflating it and then release a little bit of air for my preferred 'hardness'. Since this is the short version, the legs are outside the mattress. Some might take some time and adjustment to get use to it. Pretty durable so far.
Some air leak out by morning. Compact for easy travelling.

As the title says. I didn't have any problem with deflation using it in a tent with no pad. It lasted up to 9 hours without any noticeable deflation. Good product

What is the r-value?
The R-Value is a measure of the thermal insulation. It measures the ability of a mattress to retain or prevent heat from escaping from a warm body (human body) to a cold floor. The higher the R-Value, the better the insulation of the mattress. Please note that the R-Values can be added; this means that you can use 2 mattresses and add their R-Values. All of our mattresses are tested according to the ASTM F3340-18 standard.
What r-value for what use?
R-value from 0 to 1.9: Hot season (summer) only R-value from 2 to 3: 2 or 3-season (spring-summer-fall) R-value from 3 to 4: 4-season R-value of 4.5 and higher: Use in all 4 seasons and in extreme conditions (glacier, far north, and high altitudes)
Little tips for sleeping properly on your mattress
Once it is laid out, remember to adjust the inflation pressure of the mattress by lightly pressing the in valve (cap open). A mattress that is too hard often causes discomfort. There are silicone patches on the top of the mattress to stop your sleeping bag from sliding across the mattress.
Additional sustainable development information
Textile dyeing requires a lot of water but also produces waste water from the dye baths. To reduce the environmental impact of this model, we chose to use a dyeing process called "bi-ton" which involves dyeing 1 out of every 2 yarns. This dyed yarn is also made from a bulk dyeing process which incorporates the color pigments from the yarn manufacturing phase onward. This process reduces the CO2 emissions of this product.
How to fix a leak on your mattress
An inflatable mattress is not puncture-proof but it can be repaired! When using it, take every care when installing and handling it. In the event of a problem, we recommend using self-adhesive repair patches (ref: 8584596). For more information, copy the following link into your browser: https://www.forclaz.co.uk
