Could this replace a caravan mattress and used for up to three months continuously
Jenny - Melbourne, VIC (2 weeks ago)
G'day Jenny,
There's absolutely no reason we can think of why you couldn't. I am aware that some people have used these as a mattress at home between living situations, etc, and there's been no issues there.

2 in RV51 answer
Can I fit 2 side by side a RV5?
Rhys - Eaglemont, VIC(4 months ago)
G'day Rys,
No, you cant without the outside edges being squished in - which could be a detriment to your mats on longer trips. The floorspace measurement is slightly too narrow to begin with, but also doesn't account for the internal tent frame. You probably realistically have about 245cm of functional clear width. Hope that helps.

Which stretcher suits this best?1 answer
We have the Exped Megamat Max 15 Duo mattress. We want to get a stretcher to use with it, but none of the available stretchers are quite the right size. They're either too tall & wide (Oztrail & Kamper) or too narrow (Zempire). What would be worse - too wide a double stretcher (would we be sleeping on slopes if the mattress doesn't go all the way to the edges?), or too short a stretcher (with the mattress hanging a few cm unsupported at head & foot)? Thank you!
Jacqui - Melbourne, VIC(8 months ago)
G'day Jacqui,
I think having a stretcher that is on the narrower side would be a better option, as you know the mattress will be fully supported by the stretcher frame to each side. Generally with the doubles, I think it's a better bet to have a slightly smaller stretcher. It's just my personal preference with what I think is more comfortable, and think the Zempire would be a great choice.

Fitted Sheet1 answer
What size fitted sheet you recommend for Megamat 15?
Manoj - Kingswood, NSW(1 year ago)
G'day Manoj,
The dimensions of the EXPED MegaMat 15 Duo LW most closely resemble a standard double mattress. That would be the best sheet size to run with if you're wanting to use standard bed linen.

can i leave it inflated or deflated in a cub camper trailer 1 answer
can i leave it inflated or deflated in a cub camper trailer excellent video and advice as always
shaun - Crace, ACT(1 year ago)
G'day Shaun,
We wouldn't recommend permanently leaving the MegaMat Max 15 in your camper trailer as folding up the trailer may cause damage to the mattress. We'd recommend deflating the mat and storing it in the supplied bag for transit.

Sitting on the edges OK?1 answer
Are these OK to sit on the edges? I'm thinking about real world usage. A 6 inch high mat will inevitably get sat on the edge (putting shoes on etc, rainy days). Would be an awful shame to deform the edge or void the warranty.
Craig - Bonner(1 year ago)
G'day Craig,
This shouldn't cause any problems, the internal foam, and external fabric have a degree of stretch, and will bounce back from being sat on, rolled, slept on etc without a worry.

Leave deflated in swag?1 answer
Could I leave this deflated in our Darche Nebula swag and roll it up with the swag instead of the standard foam matress. It would be heaps easier than packing away into a separate bag
James - Cromer(1 year ago)
G'day James,
The EXPED MegaMat Max 15 Duo LW is a bonded mat, so there's no problems storing this rolled up. The only consideration maybe the extra bulk it will add to your packed swag. We haven't tried it out ourselves, so can't say for sure if it will still fit the swag bag.

What are these like in hot weather1 answer
I don’t like sleeping hot, my other mats make me wake up in a pool of sweat, my camping is mostly in northern Australia, what would this be like? All air mattresses aren’t robust enough
Richard - Mount Isa(1 year ago)
G'day Richard,
The Megamat Max has a pretty high R-value, so you might find it's a little warm in northern Australia. It would be worth having a look at the Sea to Summit Comfort DLX SI, they have a slightly lower R-value so it might be a slightly better option in warmer conditions.

Could I leave this in my RTT1 answer
I am purchasing a Dakota 1400 RTT could the exped 15 be left in the RTT deflated of coarse when packing up the RTT
Darren - Ellaswood(1 year ago)
G'day Darren,
Unfortunately, you won't be able to leave your MegaMat Max 15 set up inside a rooftop tent without risking damage to it. We would recommend packing the mat up each time you pack away the tent.

Could you please confirm the dimensions?1 answer
I saw a review elsewhere on the internet saying that the actual dimensions of this mattress were more like 203cm x 145cm (80in x 57in) than the 197cm x 132cm quoted in the manufacturer's specs. Could you please confirm the actual dimensions, maybe by measuring a display model? I'd like to make sure it's going to fit where we need it to fit.
Phil - Gosford(1 year ago)
G'day Phil,
I've just measured our display and can confirm that the in-use dimensions are correct at 197 x 132cm.

What is the weight rating on this ?1 answer
What is the max weight for this mattress as I am about as heavy as a Sasquatch (150kg).
Graham - Glenmore (1 year ago)
G'day Graham,
Exped doesn't specify a maximum weight limit for their mattresses, however, we regularly have people buy these mats who are similar weight, and will often be sharing with another person, with no worries.

Hi I would also like to see a video I have an exped duo 1 answer
I have a duo and am looking at purchasing another for the family camping trip in the new year. I love my duo its the best nights sleep camping have ever had. I will hold out purchasing until I see a comparison. Cheers
Joanne - Frankston(2 years ago)
G'day Joanne,
Thanks so much for giving us your feedback on what videos you'd like to see from us. I've got in touch with the videography team and they've said that it's definitely on the list, though they can't give me a timeframe unfortunately. I know it's a bit frustrating, but thanks for your patience.

Comparison to the Max 10 Duo...1 answer
Can you please do a comparison with the Exped Max 10 Duo? Be great to see them side by side and their comparative packed size before making a purchasing decision thanks..
Alex - New Farm(2 years ago)
G'day Alex,
Thanks for getting in touch, the Megamat Max 15 Duo is brand new to us, so we'll ask the video team to pop it on their list. Feel free to give us a call and we can chat through the features. They're pretty similar, with the Max 15 being thicker, and having a higher R-value.
