Only downsides to a water bed are: 1. Heavy 2. You have to add chemicals to your mattress as regular maintenance 3. It can't really be extra firm (but a lot more firm than people think)

The water will steal every bit of heat from your body, but you'll stay warm with a blanket

Sometimes I can’t take a bath cause the moving water makes my head spinny. I can’t imagine how bad the water bed would feel lol. I’d probably have mid night breaks for puking.

That's a misconception for water beds.

High-quality water beds have stabilizer pads in the mattress

The idea of the old crappy 70's water bed where they slosh around is a poor idea.

You aren't laying on a ziploc bag barely filled with any water.

It's more like a ziploc bag filled with molasses. If I pushed a corner down it would slowly bring up everywhere else. If I stopped pushing a corner it everything would slowly go back down.

Say I have a massive gut and sleeping on my right side. I'm displacing X amount of water. If I was to turn to my left side I am still displacing the same amount of water. Just the empty space that use to hold my gut would be filled with the water from the other side where my gut is now. Someone on other side of bed wouldn't even feel it because the water underneath them doesn't change.

Thing must weigh like a ton and that without the gut. How do they even assemble this stuff? And whole thing sounds like an accident waiting to happen

Yeah, they can weigh up to 2000lbs with a king-size bed. A king-size bed is 6,080 sq in.

A fridge can weigh 300lb being 36"×30". 1,152 sq in.

Fridge is .26 pounds per sq inch. A water bed is .33 pounds per sq inch.

So while heavy the weight is distributed basically like a fridge. This is assuming an empty fridge.

As for durability, a quality waterbed mattress is thick. You aren't going to pop it or cut it without deliberately trying to.

Even if you took a knife and stabbed it from the top, it's not going to leak until you put weight on it.
