I'd like to experiment with a pressure mat. Inside, maybe for a couch or bed. I've seen a couple of products by United Security Products, the 901, which seems heavy duty (for outside as well), but more expensive, and the SK630, which is cheaper, but looks less durable, but might do the job.
Any recommendations?
What is your proposed use case? Also, the two pressure mats you linked to are of different sizes.
Couch, Bed. When in bed/on couch, restrict motion rule turnoff.
I know they're different sizes, but the small one, 901, gets more expensive quickly. Although the 630 is touted for outside use as well, I think the 901 would be more durable for that use. The 630 might be good enough, and cheap, but will it last?
I used one of those for a while under my doormat. Lasted about 6-7 months.
The 901 would probably be good for that, but would it be big enough? The bigger ones are more expensive. But, if you need it, and they're the only game in town...
There's a seller on eBay with several 903's, (18x24), for 50 bucks plus shipping.
Every single one of my lighter-duty ones kicked the bucket after a couple years. I’d probably opt for the more expensive one, knowing that the cheap ones are ... well, cheap! 
IRRC, @lewis.heidrick has one or two pressure sensors that he uses in his automations. He should have some good info (as usual!). 
@ogiewon as well. A whole project!
Apparently @bertabcd1234 may have thoughts on this:
I have 2 Withings sleep pads. They are excellent. Highly recommended. The sleep diagnostics are really good, and the integration from a community app here on the forum is also very good. They are a bit expensive but in my opinion worth every penny.
What do the WIthings mats do for you in terms of sleep diagnostics leading to better sleep?
I am unfortunately now on CPAP due to sleep apnea, so improving my sleep is a priority for me, given the mask can still cause issues sometimes.
Which product was @bertabcd1234 referring to in the review?
The SK630 linked in the first post.
Yep! Mine is still working for me, and I'm coming up on two years since I bought it. But my couch only gets used once or twice a week, so I'm probably not a good tester for "heavy duty" use cases. It's pretty thin, and I'm not sure I'd trust outside, at least not where it gets as cold as it does where I live.
In related news, I'm glad that Gravatar I created like 10 years ago keeps following me everywhere... 
Perhaps I should get the heavier duty model.
Curious if anyone here knows, how do the pads listed above compare to force sensing resistors like the one here? Is one of them suited for a better use case or are those resistors really just for Arduino like setups, versus the pads which use already built contact sensor inputs?
Things like this...
Yeah, I know. I need to get to bed earlier, stop browsing the Hubitat forum all night, and get up earlier and have a proper breakfast.
It looks like you'd have to have some skills to make them work.
The idea of little force sensors under the feet of a couch or bed where you could get a weight for the person or persons on it, and maybe an identity, is interesting.
Do what I do and browse the community on your phone in bed 
Though I should not be doing this either, as I am also on a CPAP machine.....
That's what I meant. It's why my sleep hours are so poor lol
