Natural Escape vs Kiwi vs Avocado Green Mattress ~For a Small Person~

Hey, I visited the Avocado store in New York a few hours ago and found the Avocado Green Mattress comfortable.
I’m interested in an organic mattress, but the Avocado Green (full size) is above my ~$1000 budget.

To decrease the chances of a return, I was wondering if someone could say whether the Natural Escape’s feel is similar to the Avocado Green, which I already like.
I’d be fine with something a little firmer as well.

The Kiwi is also interesting because (1) it’s actually in budget and (2) I’m 5’4" and weigh 115 lbs, so a kids mattress may not be an issue.
However, I’d be a little sad if I missed out on the features for achy office workers like lumbar support.
Not sure I’m tall enough for my lumbar to reach the support though. Buying mattresses online is perilous.

Thanks!
