The Serta Perfect Sleeper Select Kleinmon II Firm Twin XL Size Mattress is one of the best overall choices in the Perfect Sleeper collection, given that you like a very firm comfort level. This mattress is the second generation of Kleinmon models and contains many of the same features found in last year's line, but at a more affordable price.
If you like a very firm comfort level that's almost hard, the Kleinmon II Firm is a great way to go. With a Comfort Scale rating of 1.5 out of 10, with 10 being the softest, this model feels similar to a carpeted floor.
Time Tested Coil SystemThe 880 Edition Custom Support IWC coil system makes use of a series of individually wrapped coils to offer a high degree of body contouring, while maintaining solid support to the lower back. This system is adjustable base compatible and designed to keep motion transfer at a minimum for undisturbed sleep.
HyperTouch Comfort Will Relieve PressureThe HyperTouch Comfort System is constructed to maximize pressure relief near the top of the mattress where it's the most essential.
Feel Less Movement and Improve Your SleepUsed to make premium models, Cool Twist Gel Memory Foam promotes deep, rejuvenating rest through superior pressure relief.
A Remarkable ValueIf you're searching for a mattress that has a great combination of performance and a good price point, the Serta Perfect Sleeper Select Kleinmon II Firm is a great way to go, as long as you like a very firm comfort level.
