I'm not sure if this is the one, but you can try the Badger Basket. I own a nursery design boutique and have been sourcing products. I came across this one the other day, and it sounds like it fits your needs. Another option is the Cariboo. It is a cool little modern looking bassinet. I don't carry either of these at this time, but I wanted to let you know they are out there. :)
Also, I am headed to Market this week where about a million vendors will be there to show off their items. If I run across a bassinet like this, I will let you know!
I have a discount link on the Mom Perk page if you want to check out any other nursery items. My store is Ashberry Baby.
Good luck and congrats!
