A luxurious and extravagant mat for couples, the Sea To Summit self-inflating Comfort Deluxe SI Double Sleeping Mat is the sort of camp mat that promotes a good night sleep, and a long sleep in the following morning no matter where you set up camp.

With 10cm of highly compressible cored PU foam there's tons of insulated comfort, and when it comes to packing up, the mat compresses down to a very manageable size that will easily fit into the boot of even the smallest car... room for a few other luxuries.

Finished off with a soft stretchy top fabric for next to skin comfort, the Double Comfort Deluxe Mat SI Camp Mat from Sea To Summit is a compact luxury that fits seamlessly into any camp setup.

Was a little hesitant to spend so much money on a mat that had no reviews and such limited product detail. Glad I did. This has been a revolution in camping for us, the missus loves that her bony hips ache no more in the mornings. The top stretchy 'velour' or whatever it is is very comfortable and the foam is firm enough without being like 10cm of cardboard. Pretty much has to be stored unrolled so that it re-inflates sufficiently quickly If you store it rolled up it'll take literally hours to fully inflate on the first attempt. Can be rolled up into its bag in 10-15 minutes with minimal muscular contortions. The valves seem fine thus far. Cant comment on its durability yet as I've only slept on it a few times. But for now, this is a beautiful, squishy, reasonably supportive piece of luxuary.

Best double mat for swag1 answer

Hi. I am chasing a double mattress for my Oztrail Mitchell double swag. I prefer to sleep on my side and find that I wake up with very sore hips on the original swag mattress. So Exped, Blackwolf or Sea to Summit ?? I do like the idea of straight sides to maximise sleeping area.. Looks like spending either $350 or $500.

G'day Richard,

Comfort can be a very tricky one to answer as different people look for different things. I would suggest the best bet would be to give our customer service team a buzz on 1300 914 007 and they'll be able to talk it through with you.

How long is a lifetime?1 answer

Hi, I was wondering if you can advise how long STS expect the lifetime of this product to be for an occasional (4 trips a year) camper. Comparing this mat to the Exped Megamat Duo, which has an explicit 5 year warranty, and wondering which one to go for. Are they of similar quality and comfort? Thanks!

G'day Justin,

"How long is a lifetime?" is a pretty common question we get & to put it vaguely, it basically covers the life of the product. If at any time during its life, you see any manufacturing defects, then it's covered under warranty. If the damage is general "wear and tear" though, then it's not covered. Most things will get to the point when the wear and tear will make the product unusable. As for whether or not to go for the Sea to Summit Comfort DLX SI Sleeping Mat Double or to go for the Exped, it really comes down to personal preference. They both have redeeming features over the other.

Dimensions, bag type etc1 answer

Any further details on this mat, maybe some pics?

- Sanctuary Point(7 months ago)

G'day Troy,

The bag included with the Sea to Summit Comfort DLX SI Sleeping Mat Double is a basic polyester bag with drawstring. The dimensions are listed above in the specifications, but to confirm - that mat is 201L x 132W cm and is 10cm thick. This mat is a new product and so far this is the only image we've been provided from Sea to Summit, however, we're working on sourcing more in the very near future for our website.

What are the packed dimensions?2 answers

What are the packed dimensions? Does it come with a bag?

- Sydney(10 months ago)

G'day Sang, 

We can't seem to find those specs online, and as we don't have any stock right now we can't measure this ourselves for you. 

I've given Sea to Summit a call about your inquiry, so hopefully they will get back to me ASAP about the packed dimensions of the Comfort DLX SI Double. 

- Snowys(10 months ago)

Hi Sang, 

We haven't been able to get our mitts on that info for you, generally, we independently measure all our products for packed size, and so as we don't have stock we haven't got that spec up yet. 

If we had to take a guess, it would likely be a similar height and width to the single size, so about 18cm in diameter and 132cm long. 

It does come with a bag, but it doesn't have a carry handle Sang.
