There is a reason to build stairs like this. They use less space. Almost 50% less

And you can adjust your balls as you climb. This is a masterpiece.

Don't try to climb them while drunk off your a$$.

Imagine that as a spiral staircase

Yeah but you can't slide down them on your backside. Not that I still do that...
*Sneakily stops sliding down my stairs*

may use less space, but the downside is that it becomes extremely steep and can make it awkward going down

Imagine being a grandparent trying to get up those steps.

But what if you're left footed?

what if i fell i would probably die.

i trip on stairs way to often to risk something like this....

Good luck moving a bed or sofa upstairs, or even worse, downstairs

no

Don't miss a step coming down, lotsa painful corners.

Much more dangerous, not practical.

well, if you're gonna walk up the stairs more than twice a day, wouldn't it be actually a good idea to make them walkable instead of desperatelly try saving on space? if you're so concerned about space, what about a bloody ladder, then?

Imagine accidentally falling down the stairs, Ouch

Stairs should always be able to turn into a slide with the use of a small mattress. Therefore the only really definitive measure of a staircase is how much fun a your staircase slide is and that space saving abomination is a trip to the ER.

We have a ladder like this in the resort I work at and these are the most annoying things to walk up or down, especially while carrying something. I can't tell you how many times I stumbled on these damn things.

And how most people run up and down the stairs... good luck running down them

I don't think I would have those. May be cool but way to dangerous.

Jesus goddamn they take up less space! I believe you, there's no need to get math involved

It's literally just built on a steeper incline than regular stairs

its not even safe. its less space but dangerous enough to send you straight to the hospital and cost more money. safety > money

Yes but 50% more people die on this stair case than on the original

You would have a fantastic legs on those stairs
