I weigh 400lbs and my husband weighs 300lbs and we have had no issues whatsoever. It's AMAZING! We've had it 3 years without any problems supporting our weight or hanky panky movements. :D

I ordered this one from Amazon. It has a weight capacity of 3000lbs. It was easy to put together and really strong. I’ve had it since November after purchasing a Big Fig mattress and I’m really happy with this frame so far. My husband is about 350 and I’m 280. Plus the mattress weighs another 100lbs or so.
