G'day Don,

Yes, the coupler kit will work quite nicely with keeping the Monstamats together!

G'day Claire,

It wont work at all sorry.  The Exped Universal Mat Coupler is designed for joining 2 single mats only.

G'day Neil,

The Universal Mat Coupler Kit should work ok with a tapered style due to the loop adjustability. As long as you don't put too much tension on the strap at the tapered end I think it should stay in place ok.

G'day Remote Offroad,

I've just double checked and the Exped Universal Mat Coupler Kit are only compatible with the single mats (Megamat 10LXW). 

G'day Emmanuel,

I've just given this a whirl for you and managed to get the Exped Universal Mat Coupler Kit to work with the Darche 900 Mattress. The Coupler Kit has a couple of velcro tabs that you can use to shorten or lengthen the loops. Just make sure they're loosened to fit your Darche Mattress in. 

G'day Kyle,

The Exped Universal Mat Coupler Kit is designed to be able to be used on a range of different mats and they are adjustable. So you should have no worries with using it on a couple of king single Oztrail mattresses. 

G'day Martin,

You can definitely join mats of different sizes together with the Universal Mat Coupler Kit, as the middle band and loops on either side are adjustable. There’s a good video that shows you how it works which you can check out here for reference. 

G'day Mark, 

I can see why yo'd be a little confused there, but I've just double checked and I've found you only need one kit, as each one comes with two seperate loops - one to loop around the mats at shoulder height, and the other at hip height.
