What is the opinion of Reddit about the
Zinus Michelle Compack 9-Leg Support Bed Frame, for Box Spring and Mattress Set, Full, Black (AZ-SBF-07F)?

Here is another option while you wait for your bed frame. To get your mattress off the floor you could order this from Amazon & return it in 30 days. By that time your frame may come. Just make sure it’s shipped & sold by Amazon not a third party seller. Just an idea.

This is the frame I have for my full sized bed.

The way it looks is why I need a box spring. Or will the mattress alone be enough for something like this?

So, bed frames meant to attach a headboard, have 2 flat brackets to attach a headboard. Since you have baseboard heat, you want any flammable materials 8 inches away from the heating unit. This also allows proper airflow so it can actually heat the room.

You can get a frame and headboard separately. You just need a frame with the bracket to mount a headboard. Zinus Compack 9-Leg Support Bed Frame, for Box Spring & Mattress Set, Full https://www.amazon.com/dp/B00EYN1NT6/ref=cm_sw_r_cp_apa_i_D5i8Ab1TDEM7F

Many beds don’t use box springs and their frames are platforms for the mattress Zinus 14 Inch SmartBase Mattress Foundation / Platform Bed Frame / Box Spring Replacement / Quiet Noise-Free / Maximum Under-bed Storage, Full https://www.amazon.com/dp/B006MISZOC/ref=cm_sw_r_cp_apa_i_x7i8AbVQ9TGA5

You can also buy a bed with platform frame, headboard and footboard. https://m.ikea.com/us/en/catalog/functional/10376/16284/

I’d suggest you determine budget and style choice then look around.
