Conclusion
The Harmony Lux Hybrid Trilliant Firm mattress from Beautyrest features Seaqual technology for better sustainability. This hybrid mattress has cooling qualities, plenty of pressure-relieving foams, and a pocketed coil support system.
The gel memory foam is the trick to this mattress being both firm and extremely comfortable. It allows for that dense feel while also contouring to your body so there are no jolting pressure points. The pocketed coils also help, as they can pinpoint support right where you need it with no stiffness. They're also good for reducing the transfer of motion (great if you sleep with someone).
On the firmer side, the Trilliant Firm will likely not work well for side sleepers, who need a bit more cushioning. However, if you sleep on your back or stomach, it could be a match for you. Try the medium and plush versions if you need a softer mattress.
I think the Trilliant Firm will be a hit among back-sleepers! If you love a firm mattress, this hybrid is a wonderful high-end option that I recommend.
