Wife, Mummy, Nurse: OsoCozy flat diaper review

OsoCozy flat diaper review

For the Flats and handwashing challenge organized by Kim at Dirty diaper laundry, I received 6 bleached flats and 6 unbleached flats from OsoCozy to review.  The website states that prior to washing them, they are 27 inches X 27 inches (unfortunately, I did not measure the flats before prepping them).  After prepping the diapers and using them for over one week, the unbleached flats are 28 inches X 23 inches, and the bleached flats are 26 inches X 23 inches.  I don't know why they are different this way, but I measured multiple flats of each kind.

Bleached flats have been bleached at a factory and therefore they are white in color.
Cons of using bleached diapers are:

  • The strength of the fibers is weaker because of the bleaching process.
  • I noticed the bleached diapers were getting pilly.
  • Additional pollutants can be released in the air due to the bleaching process.


  • Faster prep time.

Unbleached flats have not been bleached at a factory and have a beige color.
Cons of using unbleached diapers are:

  • More prep work because they have retained their natural oil.  I washed and dried my unbleached diapers two more times than the bleached diapers before using them.

Pros to unbleached diapers are:

  • They are better for the environment since they have not been bleached.
  • They are softer due to retaining oil 
  • Hide stains better because of the beige color.

The biggest drawback I found by using OsoCozy is that they are a smaller size than other flat diapers on the market.  I don't see them working for a bigger baby until they are potty trained.  My daughter is 9 months old and is 27 lbs. and 31 1/2 inches long.  Her rise is about 19 inches, and her waist is 22 inches.  For the diapers I received, I had to partially overlap two diapers before doing either the kite fold or origami fold.  Though, I found that they pad fold worked well for us.

Overall, I did not have a problem with absorbency (except for Day 2).

Based on the pros to using unbleached diapers and the bigger size of the unbleached flats, I would recommend to my readers if they were to buy OsoCozy flats, that they buy the unbleached flats.

Note: I received 6 unbleached flat diapers and 6 bleached diapers from OsoCozy to use during the Flats and Handwashing Challenge and reviewing them.  I was not compensated in any way.  My review on this product is reflects my experience with this product.

  1. We used Diaper Rite unbleached. It did make for more prep work but it was worth it. And our flats were huge - like mini-table cloths.

    Your daughter is 7 months younger than ours about the same size. Our bean is 20lbs and 30 1/4 inches. We struggle with her waist and getting covers to fit her. Then, I'm only 5 feet tall so she's probably going to be a small person, too.

    Good review.
