G'day Roland,

It's impossible to say really, the foam in a swag mat is open cell and constructed quite differently to self inflating mats of similar thickness.
I'd say you're probably looking at around 2 as an absolute guess.
You can help raise that by using a yoga mat or something similar underneath, or even folded woolen blankets.

G'day Ike,

Cold water hand wash, or gentle/handwash cycle in the washing machine.  Best to also line dry so the cover doesn't shrink.
Bare in mind it can be abit of a pain to get the cover back on, so using a fitted sheet or doing a spot clean would be ideal first options.
Hope that helps.

G'day Rich,

Yeah, there's no reason why you cant roll these mattresses up.  Bear in mind though that they are just a slab of foam, so may take some effort to get t it rolled up, and I would recommend using 2-3 straps instead of 1 - otherwise the ends will spring open like a bow tie!

G'day Sam,

The 110 Wide Swag Mattress comes in two thicknesses, 50mm of 70mm, either side of your old mattress. They are 215L x 110W cm, so a tad larger than your current swag mattress. The mattress has a zippered removable cover that can be removed for cleaning.

G'day Rod,

This Swag Mattress doesn't come with a bag as it's designed as a replacement or extra mattress for your swag. The All Terrain mattress comes with a bag and uses high-density foam that is a little thicker than the Swag mattress. In terms of comfort, most people report that the All Terrain is a little firmer but more comfortable overall.

G'day Sarah,

We have had a few people upgrade their old 50mm mattress to the 70mm, or add an additional 50cm mattress, but I've not had anyone opt for the extra 70mm mattress to make a 120mm total thickness. You should be ok to roll this up, but you might take a few goes to roll it up tight enough to secure.
