At 16 inches tall, the Organica Plush is indeed a substantial mattress, which might be a concern for some users. If you find the height challenging, there are a few potential solutions to consider. First, you might want to invest in a low-profile bed frame or platform to reduce the overall height of your sleep setup.
If mobility is a concern, you could also consider using a step stool to make getting in and out of bed easier. However, if these solutions don't work for you, you might want to consider the standard Organica model, which is 13 inches tall, or explore other options that better fit your needs and preferences.
