Here are some alternatives to the everyday chair at varying price points that I think you will like...
Bovist Floor Cushion
Charles Ghost Stool by Philippe Stark for Kartell
Knitted Pouf by CB2
For less than $100, this pouf is a great addition to any room in the home.
Butt Low Stool by Established and Sons
The best thing about these stools, other than the fact that they are absolutely adorable, is that they are stackable. So, for those urbanites this is quite the sensible option.
Primary Poufs - DWR
These poufs are great because they are made for the outdoors so they are very durable. I have them in my backyard and we use them for extra seating as well as a place to put drinks and food. I also think they would be super fun indoors as a night table in a child's room (no worries about sharp corners!)
Platner Stool by Knoll
How beautiful is the Platner collection? I really want a Platner lounge chair or the coffee table for my next design project. I would love to see the stool upholstered in a hot pink velvet.
Tatino by Enrico Baleri & Denis Santachiara
Are these stools just the cutest looking seats you have ever seen? Love the bright bold colors....
Apple Small Beanbag - Eazybean
Eazy Bean is a wonderful resource for children. Their beanbags and floor cushions are both fashionable and functional.
Rose Cube Pouf by Missoni Home
Erbario Giant Round floor Cushion by Missoni Home
While Missoni clothing is not my style, their home line is by far one of my greatest design obsessions. From their bath towels to their fabrics I just die (feel like Rachel Zoe writing that!)
