You can buy the frame with both headboard and footboard attachments. I've always used metal frames and have never found them unstable. Just be sure to buy a good one! I'm not sure how you're setting up the bed, but daybeds usually have a back (headboard) along the long side of the bed and then short sides on each end (looks more like a sofa). Here is a link that might be useful: Frames

I love the first one for a little girl and it will look great without a footboard just with that pretty headboard by itself. It will look even prettier if you have an eyelet bedskirt or some kind of bedskirt that is white. I have a bed with an Rustic Ivory Iron Headboard with no footboard due to the size of my bedroom and I am very happy I chose no footboard to make my room appear smaller with less walking room. If I had a big bedroom, I would love a footboard. I also had a Stanley Fiasco and despite missing the styling of the Cottage Revival Furniture (I loved the bun feet and beadboard sides that were really veneered wood over particle board but pretty.... I do not miss the mismatched furniture, peeling paint, spintered and chipped runner, holes in back of bureaus, and many other quality control issues) , I love the fact that my solid Maple Wood Durham Furniture (Royal Cottage in Sand White) came to me in such wonderful shape and MATCHING and did not waste 2 weeks of my time due to the poor quality control from Stanley and the Kearny, NJ store actually allowing furniture that was so mismatched in color with so much damage to be delivered to my home. I sure wish I found my new retail store in Flemington, NJ first since I am sure (based on what they told me and seeing how wonderful they were with my Durham Delivery) they would have never let furniture with that quality enter my home based on what they have told me when I showed them the pictures of the Stanley Furniture. Also The Durham furniture was ready in 6 weeks rather than 11 weeks like the Stanley Furniture.

The language of feng shui may sound a little woo-woo to those of us with a Western education and mindset, but from my limited reading about it, a lot of it seems firmly rooted into the psychology of how we relate to spaces and objects (real or perceived), sometimes rooted in a very primitive part of our brains. Like when my bed was oriented so my head was opposite the door. Or sleeping underneath an object or architectural feature that give the impression it could fall on you.

I would still recommend a headboard as well the pillows. It wouldn’t take up more than 5” or so of the depth of the room. You have the height for one. It will make the room feel much more finished. Also, if it’s upholstered, it’s another supportive layer.
