I purchased two of these for a day bed + trundle and they worked out perfectly. The name brand is actually a bit misleading because it's a mattress made by Sleep Innovations being sold by Serta under the Serta brand (the packing documents make that clear). That said, the mattresses arrived tightly compressed in two big 2'x2'x4' boxes, were easily unpackaged, decompressed, and allowed to air out for a couple days before getting used. There was a strong odor at first, but it dissipated. They are very comfortable mattresses so I'm hoping they stand up well over time. The only negative that comes to mind is that the mattresses do not have reinforced edges so there's not as much support if you're sitting on the edge of the bed. Many mattresses lack this feature until you spend a little more, though, so it's still a great bargain and a simple compromise. Moreover, the lack of edge support actually works out great, possibly better, for popping up the trundle and making a "short" king out of the daybed without having a hard seam between the two mattresses. In all, a great deal and comfortable mattress.
