I didn't see your original post but outdoor pillows sound like they would be uncomfortable to use indoors, especially on a comfy sofa.

And there are too many, plus they are on the smaller side. Yes HGTV shows use a ton, but that is for staging purposes. No real home needs 16 pillows on a couch. Plus, like I said those pillows they use are larger. I would limit your pillows to 2-3.

my rule for pillow count: if anyone has to remove more than one to sit down, you have too many.

I'd remove the turquoise pillow. I have 5 large pillows on my sofa since it's pretty deep (which may have been a mistake as we require the extra pillows for comfort), so the pillows are never removed.

that is my thinking, too. its not the actual count that matters, its the inconvenience of moving whats not necessary for better function.
