Twin XL

Crafted with aviation-grade memory foam infused, its optimized internal pore structure delivers supportive comfort while maintaining superior breathability.

I got this memory foam mattress topper for my child’s dorm room. She won’t be using it until this fall, but we took it out to air out, try out and show you the entire product. We’re then going to wrap it up until autumn. There’s no strong odor which is a plus. It looks bent because it just came out of the box and hasn’t been slept on. Just needs some time to fluff up. She did lay on it and says it seems soft and comfy. Nice product and fits my daughter’s needs. Whole product photo and close up so you can see detail.. Jessica. Albuquerque, NM. Thu Mar 12 2026

CertiPUR-US & OEKO-TEX Certified | Fibreglass-Free | Medium Firm + Extra Firm

Absolutely amazing bed! I had it I’m on the firm side for a week and thought it was a good firm bed, then I remembered that it is flippable! I switched to the more plush side- no regrets on buying this bed! Super comfy! I LOVE it! ❤️ 10/10 reccommend.. Cassandra. Janesville, WI. Sun May 10 2026

Please allow 24 - 72 hours for your mattress to regain its full shape. Any memory foam will expand faster in a warmer room. The expansion time of the mattress will vary as per the surrounding

The packaging was simple and easy to open, which I appreciated right away. Unlike some boxed mattresses that practically explode the moment the plastic is cut, this one expands in a much calmer and safer way. It slowly drew in air and took about two hours to really look like a mattress, then continued settling overnight until it reached its full shape. Comfort wise, this mattress definitely lives up to its extra firm description. It has very little give, yet feels supportive rather than hard. The breathable foam construction also helps it feel comfortable through the night. I chose the 10” thick version and think it would be especially good for a bunk bed, daybed, trundle, RV, or guest room where a dependable low profile mattress is needed. Overall, it’s a straightforward comfortable extra firm mattress that does exactly what it’s designed to do well. Practical and easy to use. Ideal for an extra bed used for short term guests..
