The Downmat 9WL feels very much like an inflatable air bed to me. It's very scrunchy when you move about, this may be down to the tubes down it's length.
Inflating it means giving it CPR for about 10 minutes.
On the plus side, it is warm & can be folded down the middle before being rolled up.
The Megamat is like being in bed at home. It has a soft velour feel, and the way the sides are vertical means you never feel like you're rolling off it.
I have mine so loose it can actually be folded in half. But when you lie down it just spreads your weight perfectly with no lumps, squeaks or rough edges.
The supplied pump is better than the integrated jobbie on the Downmat, but still nothing special. As mentioned earlier, the schnozzel bag would be quicker for both, but I spent the extra on the Exped pillow .... which is also great.
The Megamat I would replace without question (despite the 50% price hike since I got mine 6 or 7 years ago). The Downmat probably not so, due to such infrequent use and stiff competition at a much lower price.
