About this item

Highlights

  • 【Targeted Comfort & Advanced Motion Isolation】 Experience relief at key pressure points with the GelFusion Gel Memory Foam layer, which contours to your body in this Hybrid Mattress. Beneath it, our MotionLock Individually Wrapped Pocket Springs are tuned to minimize motion transfer across the Bed Mattress and provide responsive, zoned support for undisturbed sleep, defining the quality of a premium twin mattress.
  • 【ShadowBreeze Comfort Surface: Engineered for Coolness & Safety】 The ShadowBreeze performance-knit fabric incorporates advanced thermo-regulating fibers to enhance airflow, making it a Cooling Mattress surface. It provides a Soft, durable, and skin-friendly feel. Certified to CertiPUR-US standards, it ensures a healthy foundation for a twin memory foam mattress, free from concerns like those associated with some Memory Foam Mattresses.
  • 【Breathable Side Mesh Enhances Dual Cooling】 The breathable mesh sides promote continuous airflow to vent heat. This works in tandem with our two core cooling technologies: the ShadowBreeze fabric and the Gel Memory Foam layer. This open-cell, Cooling Foam circulates air and dissipates heat efficiently, preventing heat buildup for a consistently cool sleep on a twin size mattress.
  • 【7-Zone Support for a Balanced, Medium-Firm Feel】 Our Shadow S-Support Core is engineered with seven precision-calibrated zones to provide targeted support for back pain relief. It maintains alignment for the lumbar region while ensuring balanced comfort, achieving a supportive Medium Firm Mattress feel. This makes it an ideal firm twin mattress for those seeking firmer, aligned support.
  • 【Find Your Fit Risk-Free: 110 Nights, On Us】 Sleeping preferences vary. That’s why we offer a 110-Night Trial on this twin Mattress in a Box. Your mattress in a box ships directly—unbox, allow 72 hours to expand, and try it. If it’s not your perfect fit, we arrange a hassle-free return.

Finally found one that doesn't hurt my hip

I'm a side sleeper with arthritis and finding a mattress that doesn't hurt my hip has been a nightmare. This one surprised me. The top is soft enough but not too soft, and my lower back doesn't ache in the morning like it used to. I was worried about the price but my daughter told me to just try it. Glad I listened. It doesn't sleep hot either — that was a big one for me. Took a couple days to fully puff up but no smell at all. Feels solid. Would recommend for anyone with joint pain.

Was not expecting this much comfort for a Twin

My son is a picky sleeper and honestly so am I when it comes to spending money. This one was a little more than I wanted to pay but whatever — he sleeps hot and his old mattress was trash. This one actually keeps him cool. No more coming in at 2am to find him sweaty. He says it's comfy and not too soft. Set up was easy, no smell, puffed up quick. Feels way more expensive than what I paid. Would buy again.

Best mattress I’ve bought so far

After sleeping on this mattress for a few weeks, yeah it's totally worth it. You definitely get what you pay for. First off, the cooling actually works — I'm a hot sleeper and I don't wake up sweaty anymore, which is huge. The Euro top is plush but not like sink-into-it soft. And the 7-zone support is legit; my lower back used to hurt from cheaper foam mattresses but now it's gone, and my spine feels good whether I'm on my back or side. It puffed up in about 48 hours and there was no weird smell either. For a 12-inch Twin hybrid, this thing punches way above its price. Yeah it costs more than the cheap ones but seriously feels like a $500+ mattress. Highly recommend.

Gaming setup upgrade

Spent all my money on a fancy PC and chair but was still sleeping on this ancient spring mattress from college. Finally pulled the trigger on this 12-inch Twin and my only regret is not doing it sooner. The medium-firm is perfect for crashing after all-night sessions—my lower back doesn't feel broken anymore when I finally peel myself away from the screen. The cooling actually works too which surprised me because my room gets hot with all the gear running. Unboxing was easy enough just rolled it out and let it do its thing. Yeah it cost more than the budget options I was comparing but I've wasted money on enough junk that falls apart in six months. This feels solid. Sleep is finally part of my setup instead of the weak link.

Great Comfort and Support

I’m really happy with my Quilicore Twin XL mattress. The medium-firm Euro top feels supportive yet comfortable, and the gel memory foam does an excellent job relieving pressure on my shoulders and back. I sleep more soundly now, and motion isolation is impressive — I barely feel movement during the night. It expanded quickly, looks high quality, and feels like a premium mattress at a great price. Highly recommend!
