The Serta Cascade Canyon Medium Mattress in Twin XL delivers personalized support through its innovative Q4 Support System, featuring 860-density coils that work together to evenly distribute your weight throughout the night. The mattress's 5-zoned comfort design alternates between firm and plush areas to naturally contour to your body's curves, providing targeted support exactly where you need it. Designed with cooling in mind, the CoolFeel fabric and CoolTwist gel foam work in tandem to pull heat away from your body and promote airflow, helping you maintain a comfortable sleeping temperature all night long. This medium-firm mattress strikes an ideal balance for side and back sleepers seeking both cushioning comfort and reliable support that lasts.

Rated 5 out of 5 by from Supportive [This review was collected as part of a promotion.] This is such a nice mattress. I am primarily a side sleeper and find that this mattress provides the necessary support. It comes as an actual mattress, not a foam one that expands, so keep that in mind when you are getting it. I have only been using it for a short time, but it seems like great quality and that it will last. A little more expensive than a boxed mattress but a great price for a name brand mattress.

Rated 5 out of 5 by from Medium Firm Support is perfect! Not too firm, just right.

Rated 5 out of 5 by from Sturdy, comfortable, and supportive - I'm getting better sleep. [This review was collected as part of a promotion.] I paired this medium firmness queen size mattress with a Serta queen standard foundation and my bed feels sturdy and comfortable. The comfort zones are one of the first things I noticed when trying it out; while lying on my side or back the mattress allows for my body's curves and still supports my back. Upgrading after using a foam hybrid mattress: it's easier to fall asleep because this Cascade Canyon mattress is cooler, soft and supportive, and I'm noticing fewer aches when waking up in the morning. Overall I'm super pleased!

Rated 5 out of 5 by from Luxurious and supportive mattress [This review was collected as part of a promotion.] The Serta Perfect Sleeper Cascade Canyon medium mattress is high quality. The cover of this mattress is soft and cool to the touch. The 4 in 1 coils support system evenly distributes my weight. I appreciate how this mattress conforms to different sleep positions. I put this mattress on a low profile Serta box spring that’s a perfect combination. The counting sheep that are hidden on the mattress top is a fun addition. I’m looking forward to many years of restful nights on this mattress.

Rated 5 out of 5 by from Extremely Comfortable Mattress with Great Back Sup [This review was collected as part of a promotion.] It was time to level up our bed, and this is one of the nicest mattresses I’ve ever owned! It’s extremely comfortable while still giving me the back support I need - as someone with chronic back pain, this is something I value highly and take into consideration when purchasing a mattress. I keep the house cold at night because I’m usually a sweaty sleeper, but I’ve stayed a comfortable level of cool throughout the night while sleeping on this mattress - which could also be in part from the sheets I’ve paired with it! The edge of the stitching around the mattress shows me that it was very well made. I will definitely get any future mattresses from Serta if it holds up well over the next few years!

Rated 5 out of 5 by from Great Quality Mattress [This review was collected as part of a promotion.] This is a great quality mattress! It is super thick and supportive. The team that brought the mattress in were quick and professional it was fantastic! I slept so well and i don’t need to use my mattress topper anymore it is comfy enough on its own!!
