Our Verdict
Beautyrest Harmony Lux
Boring Mattress
The Boring Mattress and the Beautyrest Harmony Lux seem well matched, but the Boring has an advantage that makes it the better choice for most users. That advantage is in the density of the foam, which correlates to quality and durability. The Beautyrest uses low-quality foam throughout the mattress, making premature indentations and sagging very likely. Conversely, the Boring uses good and high-quality foam, which extends the life of the mattress overall. So, if durability is a consideration, the Boring is the better choice. If you're not concerned about longevity, either mattress should suit you. The Boring has a slight advantage in cooling and motion dissipation, while the Beautyrest has better edge support, but there's not a huge difference in any of these areas.
