Never Again

I bought one of these hopeful of a good nights sleep, unfortunately it wouldn't stay inflated, when I got home I filled a bath with water to find out where it was leaking. To my surprise it was more like where it wasn't leaking, all the corners leaked in numerous places top and bottom where the seam meets the inflated area, 33 holes in total. When I tried to return it to the store I bought it from I was told by the Customer Asst. that it wasn't for water use and as I had exposed it to water I couldn't get a refund or replacement. When I asked to speak to the manager the Customer Asst. called the security staff over and had me removed from the shop. This is the worst customer experience I have ever had! My recommendation is to not buy from this company ever!

overall great

Size better than L size comfortable and compact

Dear Kawaily, thank you for your time in leaving us with a 5-Star rating on our Self-Inflating Trekking Mattress TREK 500 XL.

Please let us know if there is anything else we can improve on in the future. Thank you once again for your time and we hope to serve you again soon!

Amazingly comfortable

Unlike the regular thick air bed, this thin layer of mattress requires min effort of inflating/deflating which makes it so convenient to carry around. It's perfect for picnic, overnight camping or airport layover. Surprisingly the non slippery texture is also very comfortable to lie on. So far i have only tried it on flat surface, not sure if it is suitable to be used on rough and uneven terrain.

light and easy to use

Light enough to carry. Easy to inflate. Keeps you warm. It’s not as soft as other inflatable beds. Can be uncomfortable if you are a side sleeper but it will do. The convenience of less things to take with you is a plus. Also looks durable

Worth it! Durable!

Bought ours October or Nov 2017 and still works fine. Bought this for an out of town trip since we need to save space in our luggage. It was worth it and we have been using it ever since. Downside to this product is that the "self inlating" part take a long time we needed to pump/blow in air a few times to get it inflated which didn't take much effort anyway, the cap/opening sometimes leak air you just have to secure it everytime. We lost our drawstring pouch/bag since a few months back but overall.. It served its purpose and I think its worth the price and worth purchasing

Sleeping in comfort!

Easy to inflate. It held air all night and I was able to comfortably sleep. In the morning I was able to easily deflate and roll back up a place into the compression bag in came with. With the separate one way valves for inflating and deflating is the key to not losing air when inflating, and ease of deflation.

The principle of a self-inflating mattress

A self-inflating mattress consists of an airtight envelope glued to an open cell foam in which the air circulates. When you unfold your mattress, it will return to its original shape and thickness (2.5 cm for the MT100 mattress) and fill with air. However, it requires some mouth inflation so you can adjust it to the pressure level suitable for you. Self-inflation is more or less noticeable depending on the thickness of the mattress.

Easy inflation/deflation

When using your mattress for the first time, unroll it, open the valve for 24 hours on a flat surface, then inflate it and leave it for 24 hours, valve closed, under pressure. Then you can store it away again. While trekking, take out and unroll your mattress as soon as you set up camp, valve open to facilitate pre-inflation. A self-inflating mattress inflates to about 60 to 70% on its own. You will need to blow up the rest yourself, so you can adjust the pressure to your desired comfort level.

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 two mattresses and add their R-Values.All our mattresses are tested to standard ASTM F3340-18.

What r-value for what use?

R-value from 0 to 1.9: Hot season (summer) onlyR-value from 2 to 3: 2 or 3-season (spring-summer-autumn)R-value from 3 to 4: 4-seasonR-value of 4.5 and higher: Use in all 4 seasons and in extreme conditions (glacier, far north and high altitudes)

Tips for sleeping well on your mattress

Once you are lying down, remember to adjust the inflation pressure of the mattress by slightly pressing the IN valve (open cap). A mattress that is too hard is often synonymous with discomfort.Silicone patches on the top of the mattress are designed to reduce the sliding of your sleeping bag on 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 one out of every two yarns. This dyed yarn is also made from a bulk dyeing process which incorporates the colour pigments from the yarn manufacturing phase onwards.This process reduces this product’s CO2 emissions compared to the previous model.
