This is a quality Beautyrest mattress set but be warned: it is NOT extra firm. I bought it without actually trying it, which I wish I had. I think the majority of customers would be very pleased with this product. I just wanted something a lot firmer.
The purchase through Overstock went without any issue...after having mattress for more than six months now, the top "memory" foam padding has sagged and is prominently flattened. Mattress provides great firm support but because of top padding, mattress can't be flipped to even out wear. Don't expect it to last very long. Body weight of both people is under the average and amount of time on mattress is not long so padding should be holding up. This is supposed to be a top manufacturer and would have hoped for a long-lasting product. Disappointed with purchase.
