Does this memory foam mattress need a box spring?

No box spring is needed, and a traditional bouncy one can actually harm an all-foam bed. This Tempur-Pedic Tempur-LuxeAlign 2.0 soft memory foam mattress wants flat, continuous support: a solid platform, a closely slatted frame, a flat foundation, or an adjustable base. If you use slats, keep gaps under about 3 inches so the dense TEMPUR core stays fully supported and does not bow over time.
