After numerous problems with my new brass bed, including the center portion caving in due to lack of support. I have purchased a new bedframe & mattress from Robinsons.
Black metal bedframe in queen size as I already have a white metal bedframe in single size. There's not much to choose from if you don't want the natural wood look.
Thickest pocketed spring mattress available, planning to get a mattress topper later. Didn't get the hybrid mattresses this time around coz its quite expensive.
Saw 2 more metal bedframes @ FortyTwo.sg worth considering. Kitty Cat Ears in green and Seashells in gold.
