You're not going to find too many legit hardwood bed frames for sale in regular stores like The Brick, Sleep Country, Casper, etc. Best bet is buying something used if hardwood is what you want. I was trying for that myself, but ended up finding nothing. So ended up just buying a decent looking frame/headboard that's covered in a nice looking fabric.

If you just want strong, look into platform bed frames. It's stronger than slats, though you're generally limited on style and headboards that will fit.

I just got a Lodge Dutch oven instead of Le Creuset. Obviously it's still new so I can't speak to its long term durability, but so far the quality has been really good. I also bought it under the assumption that I may have to replace it within 5 years. But it was also a fraction of the price, so I could legit buy like 3 or 4 of the Lodge one for the price of the big brand name.
