What I Think of The Serta Perfect Sleeper Elite Trelleburg II Firm Twin XL Size Mattress
by Jed HarringtonWith a layer of premium memory foam and an upgraded coil system, the generation II Trelleburg Firm is a wonderful choice if you would like a firm mattress.
Firm, But Not Hard
We gave the Trelleburg II Firm a Comfort Scale score of 3 because it feels firm, but not hard. This is a good choice if you want a firm mattress and you don't want to feel like you're sleeping on a carpeted floor.
Brilliantly Designed Coil SystemThe 1000 Edition Custom Support Individually Wrapped Coil system does a wonderful job conforming to the curves of your body while ensuring necessary spinal alignment as well as less motion transfer. This coil system is a noticeable update from the gen 1 model in the previous line.
Comes With Cool Balance FabricCool Balance Fabric helps give way to a more thermal neutral sleep environment. Made from the same style of athletic material that is utilized in performance athletic wear, this material is both functional and comfortable.
Transfers Less Movement for Better SleepUsed to construct premium models, Cool Twist Gel Memory Foam promotes deep, rejuvenating sleep through superior pressure relief.
If you like firm comfort, you'll love this.The Trelleburg II is a nice upgrade from the generation 1 model and includes everything you need to start enjoying firm, comfortable sleep. This model offers a great choice and value in the firm line of mattresses on our site.
