A thick and comfortable mat that mashes the rigours of trekking with a touch of luxury, you'll look forward to resting on the Sea to Summit Comfort Plus S.I. self-inflating mat at the end of a long day of exploration.
Offering 8cm of insulated comfort with a soft stretchy top fabric, this mat is ideal for cold-climate trekking. The cored PU foam reduces weight and bulk without trimming any support or comfort and provides consistent warmth throughout the length of the mat.
What's more, the Comfort Plus SI can be fine-tuned to your personal sleeping comfort thanks to the innovative multi-functional valve that also makes inflation and deflation easier than ever.

Hi, Just wondering if you can get a womens version like the purple one on S2S's website?

The Comfort Plus mats are a unisex range aimed at general campers. The women's specific mat options are across models that are designed for light weight or performance adventures.

Air chair1 answer
Hi, could you please confirm the packed dimensions and what air chair this product works with? The notes re these in the comments are quite old and I'd like to ensure everything is still correct. Many thanks.

It depends what size mat you're looking at - the Air Chair sized are applicable for all Sea to Summit Air and Self Inflating Sleeping Mats. Regular Air Chair for small and regular mats Large Air Chair for Large mats.

Replacement bag?1 answer
Are replacement storage bags available? Mine ripped as it is such a tight fit, despite double and sometimes triple rolling it! Do you have an alternative storage bag for sale? Thanks, Sam

The Sea to Summit Stuff Sack in Medium fits the Comfort Plus SI Mat with a little more space than the original bag. It's also a slightly more robust material so should work well.

Packed size1 answer
Hi Snowy's. The packed size of this mat in large is smaller than that of the Comfort light and the basic camp mat (both also in large). Can you confirm if this is correct? Doesn't sound right as it's a thicker mat.
Jim - Perth(5 years ago)
Sometimes our website has just a touch of lag when looking at different sizes but the correct packed size of the Sea to Summit Comfort Plus SI Sleeping Mat is about 33 x 17 x 17 cm, which is a touch larger than the other two you mentioned.

Top fabric1 answer
Hi Snowyâ€™s. At the start of the year I purchased the S2S Comfort Light SI mat and although itâ€™s a great mat I didnâ€™t particularly like the fabric on top as itâ€™s really slippery against my sleeping bag and was a bit too thin for my boney hips as Iâ€™m a side sleeper. Itâ€™s been passed on to my son (7yrs old) so Iâ€™m searching for a new thicker mat for me. Is the fabric on top of this one different in that itâ€™s not so shiny and slippery? Basically Iâ€™ve narrowed it down to this mat & the 2S2 comfort DLX insulated air mat but without being able to see them in person it makes it hard to choose. Which would you go to? Intended use is for hiking, donâ€™t care about the extra weight if Iâ€™m getting a good nights sleep. Iâ€™m also looking at getting a quilt and not using my heavy sleeping bag for the warmer months so something that is also nice against your skin would be great.

I’m sorry to hear you didn’t find the Comfort Light SI suitable for your needs.
The top of the Comfort Plus SI mat is designed to have a soft next to skin feeling and it has an anti-slip print on it which should help to prevent it from slipping around. The Comfort Plus SI is 8cm thick, which should be a huge improvement from the Comfort Light SI.
Seat to Summit has a great video on this mat, which you can watch here. This might give you a better idea of what the mat is like if that helps.
The Comfort DLX is probably best if you’re going to be sleeping in very cold conditions as it has a higher R-value. But it’s also heavier and doesn’t have an anti-slip print.
From feeling them both in person and comparing the specs - the Comfort Plus SI seems more suitable for what you’ve described.
If you’re still unsure, our customer service team would be happy to talk through the sleeping mat range with you – just give them a buzz on 1300 914 007.

I have the Atom rolled out on the floor trying to decide if the large size which i want for the width. My standard camping mat that is 193 by 60 but heavy goes in quite easily with the tent set up.

I've just had a quick look at the Zempire Atom Tent we've got on display and the Sea to Summit Comfort Plus SI Sleeping Mat fit inside it, no worries at all!

Is this mat suitable for the Sea to Summit Air Chair?1 answer
Would like to know if these two items are compatible prior to purchase. Thanks.
Kath - Brunswick(6 years ago)
I've just popped down to our shop floor to give this a crack. The Sea to Summit Comfort Plus SI Sleeping Mat almost seems to be made for the Air Chair, they fit really well. I've taken a photo of it for you if that's of any help. Just send me an email if you'd like to get a copy of it. You might need to deflate the mat just a little bit before giving this a whirl though as when it's pumped up tight, it's a little hard to fold into the chair.

Do you need a pump to inflate?1 answer
Need a mat which is kid friendly - easy to inflate.
Simone - DROMANA(6 years ago)
No pump needed with the Sea to Summit Comfort Plus Self Inflating Sleeping Mat. You might just need to blow a few breaths in at the end to firm it up.
