I'd been eyeing this bunk bed, and then finally pulled the trigger. Best decision! I like that it's rated for up to 400lbs either top or bottom. Many other bunk beds are only in the 200-225 range. It's solid wood, good sturdy construction, and there were little to no imperfections upon arrival. While it did take a few hours, my husband set it up without any issues. It needed 2 ppl only once or twice during setup. My kiddo LOVES it. The recommended height for both mattresses is 5" (I think) and we found some good memory foam ones. You can go thicker, but it will diminish the effectiveness of the rail up top, or give you less room underneath. No regrets at all with this purchase! Absolutely love it.
