A thick and comfortable that mashes the rigours of trekking with a touch of luxury, the Sea To Summit Comfort Plus S.I. self-inflating mat offers 8cm of insulated comfort with a soft stretchy top fabric that you'll look forward to resting on at the end of a long day of exploration.

Ideal for cold-climate trekking, the cored PU foam reduces weight and bulk without trimming any support or comfort and provide 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.

Best mat ever!

This is the best luxury camping mat I've ever owned.

Super-comfortable and luxurious, with a top surface that feels really nice on the skin.

The only negative is that the bag is a bit small for the Regular size mat. You have to roll it up really tight to squeeze it back in the original bag. For the Large size mat, the bag fits the mat easier.

However that's the only negative. Other than that, this mat is perfect.

How to get a woman camping - buy her this!

I have had a number of different camping mats in the past. I didn't find any suitably comfortable to really get a good night's sleep.

Either they were noisy and rustled - like the Thermarest Neo Air, or the thin 3.8 cm SIM mats my hips did not like and I'd have an uncomfortable night sleep and wake up achey.

I like the Exped Megamats and Sim Comfort mats, but they were too bulky, as what I wanted was to be able to fly-and-hire-car-and-camp, and on occasion do short hike-ins.

This mat is perfect. You get all the comfort benefits of the large Megamat style mats, in a much smaller package. A comfortable fabric sleep surface top, with 8 cm (yes 8 cm!) of thickness from memory foam with air pocket cut-outs. All at a respectable pack-down size of 27 x 15 diam for the regular, or 33 x 17 diam for the large.

This mat was honestly as comfortable as my own bed at home. So if you want to get a woman out camping who hates uncomfortable mats, this mat is absolutely deluxe. I own the bulkier Exped Sim Comfort 7.5 and find this Sea to Summit Comfort Plus SI Sleeping mat more comfortable than that!

So are there any cons, you ask?

A couple.

To roll it back into its little bag, you need to do two rolls of getting the air out. First roll out the mat with the one-way valve. Then have a 2nd go at it, whereby you fold it in half horizontally and roll it up a second time. I've read reviews of people who couldn't get it back in the bag - that's how you do it. (Although you should store it at home in its uncompressed open mat state, like under a bed opened out, and only pack it when you're going camping.)

It seems pretty durable, and it's 30D fabric rather than 20D. However if it does spring a leak, there isn't an enclosed repair kit.

At 900 grams for the regular, and 1.2 kg for the large, it's heavier than a lot of the modern-day hiking mats which are at 350-550 grams. And it's considerably bulkier than the air mats.

However if you love a woman - or the woman loves herself - and she loves comfort - this is the mat!

Ultra-comfortable, much lighter and smaller than Megamat models, and within the realm of possibility to take hiking. (I personally rather pay the weight penalty and take this, and save weight elsewhere like with a down quilt rather than heavier model sleeping bag. However I am using the mat mainly for fly-and-car-camping, and only a little bit for hiking and mostly overnighters.)

Best Sleeping Mat Ever!

I have in recent times slept on a range of thermarest mats but this new Sea to Summit Comfort Plus is amazing. Two weeks of camping and not one uncomfortable night!

Will the large fit in my Zempire Atom?2 answers

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.

G'day Pete,

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.

- Brunswick(1 month ago)

G'day Kath,

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.

- DROMANA(5 months ago)

G'day Simone,

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.
