Ipad what do I need

[imabitjealousandembarassed]

Hello I bought an ipad with a detachable keyboard and a case , the type where the screen props up.
I think I've made a mistake as I cannot use it in bed. It keeps flopping over. Is there such a thing as a really solid case that makes it like a little laptop.
I have googled but I cant find one. I have the biggest ipad . Any help gratefully received

There are loads on Amazon. They won't be Apple ones though. Mine is the keyboard with the angled flap at the back and you can use that to prop it up in bed.

This is what I've got but it's too floppy and can't get the right angle. I sort of want a solid hinged one that makes it like a mini laptop but I don't know if that exists even
