No, but I’ve had some decent results with Sleepbot, which is much cheaper (free) if you have a smartphone already. Probably doesn’t have nearly as good measurements as the mattress, and obviously doesn’t make it adjustable, but it does seem to wake you up at a good time if you turn the accelerometer and microphone sensors on. (My smartphone broke, so as yet I haven’t collected real empirical data on how well it works)
I tried SleepAsAndroid and they quality of the measurements is low (on my mid-range smartphone).
Less anecdotal: The German computer magazine did a comparison of many sleep Apps including a comparison in a sleep laboratory. Poor guy needing to sleep with all those devices in bed. The result was that the fancy curves as mostly way off the only reliable thing is start and end of sleep.
The problem with smartphone apps is that they can only measure vibration and sound. Vibration can be used to see how much you move around and sound can get to the breathing frequency.
As Gunnar already said, vibration + breathing frequency doesn’t seem to be a perfect way to measure sleep stages. The heart rate provides for better data. It would be interesting to know how fine the bed can track heart rate. If it could track HRV it would be really great.
The mattress on the other hand can measure the heart rate. At least they claim so on the website. Unfortunately the website is quite poor at providing information about the technological capabilites of the product.
Wrist-worn devices for measuring heart rate work for situations where you don’t move much like sleeping when you don’t need HRV. On the other hand some people prefer to sleep without something on their wrist.
On the other hand the bed does has features like automatically contouring the body and the ability to adjust the firmness of the bed that ordinary beds don’t have.
For the future it would be interesting to test the effect of dynamically changing firmness and see whether it provides improvement with topics like back pain. It might be interresting to raise the firmness of the bed right before waking up.
A lot of people struggle with back pain. If the bed finds a way to relax the back better at night that can be valuable.
The application seems great, but the list of permissions it needs is scary (“perform operations like adding, and removing accounts and deleting their password”, “use the authentication credentials of an account”).
Ah, yeah, that could be an issue—I suppose I never noticed… I think there are similar apps which might not need so much information. You could google “sleep tracking apps”. Last I checked there were at least five or six similar ones.

Aren’t there wrist devices that can measure your heart rate over time? Not sure how well they work, but they might be cheaper than a gadget bed.
