The Sapphire Suite II Firm feels very firm, but has just enough padding to avoid feeling overly hard. With a comfort scale rating of 2.5 out of 10—10 being the softest—it’s easy to see that this mattress is really designed for people who know they like a very firm feel. If that sounds like you, great! You’ll probably enjoy it.

The 800 Continuous Coil Support System with Posturized Center 3rd is the best in the Serta Hotel line, and provides a very solid level of support, with extra support to the lower back where you need it most.

A double sided mattress comes with many benefits, including being able to flip the mattress whenever you like, and enjoy the fresh, showroom-like feel on the other side. Hotel’s use this design because it allows them the ability to create a more consistent experience for hotel guests. The same benefits apply to you.

If you sleep to the edge of many mattresses, you’ll feel a mixture of negative emotions, from discomfort to “am I going to roll on to the floor?” With the Sapphire Suite Firm, those negative emotions are banished, thanks to the Total Edge Foam Encasement. This edge support allows you to sleep anywhere on the mattress without noticing a difference in comfort or support, which is especially nice if you share a queen size.

While the Sapphire Suite II Firm is a top of the line mattress, in testing, it performed good for most body types and sleeping positions, excellent for petite back sleepers, and not recommended for large back sleepers. See how this mattress performed. It’s a bit disappointing to not see outstanding marks across the board, but occasionally even a top of the line model fails to hit top of the line benchmarks. If you’re looking for a firm feel that performed better, I highly recommend checking out the Serta Perfect Sleeper Hotel Concierge Suite II Firm. You’ll save a bit of money, and get better results.
