Bamboo furniture is very expensive and the conditon of yours is excellent. You should be able to get around $200 to $300 for each piece. I would actually go to an auction house in your area. You could get a much higher price for them there if they are sold off in a set.
You have my condolences on the loss of your wife. May her memory always be a blessing.
This is a very valuable brand in some settings and totally worthless in others. This is typical of furniture sales, especially something as specific as bamboo furniture.
In places like land locked areas in the mid west, people don't want it and you may fetch $25 or $30 a piece, but in places like a beach town, they can be quite valuable in the right setting (store or auction).
It is very regional and totally dependent on supply and demand and condition. Condition is especially important in these pieces and from your photos I can not assess the condition. Someone would need to sit on them to check for creaks and breaks to determine condition--these are things you can't tell from a photo. Condition issues devalue pieces like this very quickly.
If you are not an experienced seller, I strongly recommend you take these to a vintage dealer and have them value them for your town AND take care of the sale for you--either by buying outright or selling on consignment or auction.
I am an experienced seller and I always defer my furniture sales to a dealer. It just is the best way to sell it for a number of reasons....including I don't want people in my house and you have to have a way for the person to get it home since it is not small. That is always a challenge.
Please post back with an update! Thanks for sharing!!!
