G'day Ben,

It is tricky to quantify but probably not worth it from my own perspective, completely acknowledging that others may feel differently.
Theres only about 1.5cm thickness between the two, I wouldn't be able to justify investing in a second mat for such a small amount of extra 'padding'.
If you are wanting some added luxury but still within the same style of mat, check out the Comfort Plus XT.  Its slightly larger in pack size and weight, but it gives you 8cm of thickness with a bit of extra insulation.
Your almost getting the comfort specs you would expect from a self-inflating foam style mattress.
Hope that helps in some way!

Hi Chen,

Yes the R-value on some of the Seam so summit range has recently changed in line with the new ASTM testing standards. You can read more about that here.

G'day Bronwen,

You'll just need to select the small size in the drop-down menu. The small is 0.715kg.

G'day Stewart,

Sorry to hear you're having trouble with your Comfort Plus Insulated Mat. Most deflation issues with these mats will be due to a small puncture. Your best bet will be to test for a leak by inflating the mat and going over the seems and body of the mat with a small spray bottle that has a little bit of detergent in it. If you find the leak you can use the patch kit supplied to repair it. If you find the leak is occurring at the valve then snap some photos of it and jump on to our warranty claim form and the warranties team will have a look at it and advise from there.

G'day Heather,

The Sea to Summit Comfort Plus Insulated sleeping mat comes in Small (168cm) Regular (184cm) and Large (201cm). It's worth noting they're all 55cm wide except the Large which is 64cm wide. 

G'day Paul,

Whilst it doesn't really make any difference at all which side of the Sea to Summit Comfort Plus Insulated Sleeping Mat goes on the floor, if you've got the logo and the writing facing up, then it's technically the right way up. 

G'day Kate,

The Sea to Summit Comfort Plus Insulated Sleeping Mats are pretty easy to inflate, they are made a heck of a lot easier though when using a pump like the Jet Stream Pump Sack. 

G'day Kerry,

The new model Comfort Plus Insulated Mat - Regular comes with an airstream pumpsack integrated into the stuff sack. The Small and Large models currently don't, but when we run out of stock the new models will. Hopefully this clarifies it for you. If not give our customer service team a buzz on 1300 914 007.

G'day Daniel,

The main difference between the Sea to Summit Comfort Plus Insulated Sleeping Mat and the Comfort Light Insulated Sleeping Mat is the amount of insulation, yes but there are a couple of other differences too. The Comfort Plus model has 2 valves, so in the very unlikely incident of a puncture, your mat will only half deflate, giving you some comfort for the night still. The Comfort Plus also has more evenly spaced 'dimples' whereas the Comfort Light model has them more spaced out in the legs and feet. 

G'day Paul,

Unfortunately not. The mats are designed to go on the outside of the sleeping bags.
