Thanks for the response, Sensei!!!
I’m buying a full size mattress. I’m 145 pounds and a back sleeper, and my girlfriend is 125 pounds and usually sleeps on her side but also on her back. She’s not over too often because she lives several hours upstate, and she doesn’t have a car yet. Without meaning to sound vulgar, I want a frame that can handle some occasional “extracurricular activity”.
The mattress stats are: 312 coil count, bonnell springs, 13-gauge steel, about 9" thick, damask fabric. The manufacturer claims it should last up to 10 years but for the price and my life situation I don’t expect to keep it that long. (He also makes the “Body massage”, 364 coil count, bonnell springs, 13-gauge steel, about 13" thick; it’s $480 shipped which is a bit more than I want to spend for my current build.)
I am glad you linked the Magic Sleeper wire platform. According to the Amazon link, it only has a 750-lb weight capacity. The Brooklyn platform foundation is currently on sale for about $112 for a full-size – I was wondering if the extra weight capacity would help it stand up to non-sleep activities a little better? For an extra $12, I think I’d rather have something a little stronger than I really need.
Lastly, I just spoke to AA Bedding and the owner, Julio, claims that a wire platform should work just fine with his mattresses, and he usually expects them to last about 5 years, which is more than I need.
The only other thing I wanted to ask was, is there any sturdiness benefit to buying a mattress, “box spring” (really just a wood rectangle with sheets stapled to it), and a metal frame like this?
