Having moved in with Master and our Dam, It's been an eye-opening experience in terms of Master's dedication to safety, but also the man's deviousness in inventiveness.
Overnight restraints here consist of a body stocking covering one up to the neck, legs and hips exposed asid from the fabric covering one's crotch. The ends of the sleeves are sewn closed and reinforced up to the elbows.
With Hospital-issue Posey restraint mitts put on you, then the bodystocking over that...you're 'free'--but incredibly helpless.
A very deceptive restraint.
So much so that one can easily forget all about such, head into the bathroom, and only when one tries to open the crotch snaps or do anything else needing one's hands that you remember you're restrained.
Which is also somewhat frustrating!!

That said, I have learned that when one or all of us are sleeping in restraints, he stays up--watching over us. It's a new and nice thing, waking up, seeing him in the upholstered chair in the bedroom, reading or working, and knowing that all the time one was asleep...he was There, keeping us safe.
Unknown to me until recently, he checks on us also, looking at limb positions and checking pulse-point locations/circulation. Deftly enough from long practice that he doesn't disturb us.

The household's fire-suppression capacity was years ago brought to very high levels, as our Dam is a touch Pyrophobic, and when Master learned that, he made the house more reassuring with in-built, redundant, fire suppression systems.
Also, it's NOT hard to find a fire extinguisher around here and the alarm system is perhaps not the most expensive, but it is the highest rated and Redundant.

I sleep better here than I have in years, and I've always had trouble getting quality sleep.
