So I've been with my boyfriend 3 years now, ever since I met him he has always had his mattress on a box spring on the floor. I thought it was just because we were tight on $ and he didn't see the need for a bed frame. So yesterday I caught an ad of an older couple selling their antique bed frame for $100. I'm thinking this is awesome because having your mattress on the floor is not sanitary I tell yah. So I show it to him and he gives me the okay to spend MY money on it. We get home put it together and all is well. He starts jumping in it and I'm like wtf are you doing and he's like "I'm not going to careful with it just because it's on a frame now" I'm thinking do you not have any home training. Like adults don't jump in beds especially if your 200+ I have a feeling he's going to break the frame and the mattress is going to be back on the floor and I wasted $100.
