I was wondering too, but saw one of the product photos was labeled, "Bed frame available separately" so I think the answer is no, the legs don't come with.

Just spend the extra money and buy a platform bed. No more purchasing box springs and way cheaper when you just need to replace a mattress.

I recommend 14in because it makes it easy for storage tubs and luggage.

Interesting. 1200lbs capacity! Already thinking of uses for it (not involving a mattress). Given the negative reviews about shipping damage I'd opt for store pickup.

What is the point of box springs? My Granny just got a shorter one, 3", so she could get in and out of bed easier. Why not just lay some plywood on the bed slats? I know this is cheaper than plywood, but still.

Is there a difference in performance compared to a regular box spring? First time seeing something like this
