There's a slight caveat here that you are sometimes forced to effectively buy and use internet-connected smart devices if you live in rented housing and the landlord of your unit provides it. This is probably not an issue for an internet-connected bed, because conventionally a bed isn't something a landlord provides, but you might get forced into using a smart fridge, since that's typically a landlord-provided item.

I lived in a building some years ago there where the landlord bragged about their Google Nest thermostat as an apartment amenity - I deliberately never connected it to my wifi while I lived there (and more modern smart devices connect to ambient cell phone networks in order to defeat this attack). In the building I currently live in, there are a bunch of elevators and locks that can be controlled by a smartphone app (so, something is gonna break when AWS goes down). I noticed this when I was initially viewing the apartment and I considered it a downside - and ultimately chose to move there anyway because every rental unit has downsides and ultimately you have to pick a set of compromises you can live with.

I view this as mostly a problem of housing scarcity - if housing units are abundant, it's easier for a person to buy thier own home and then not put internet-managed smart furniture in it; or at least have more leverage against landlords. But the region I live in is unfortunately housing-constrained.
