It also has a "localized bounce," meaning you're less likely to disturb your partner if you share a bed — they won't feel the shift nearly as much. Arguably the most convenient thing about this, though, is that it ships in a compact box straight to your door — once you open it, you just have to wait 72 hours for it to fully expand, and voila! Plus, if you don't like it, you have a 100-day sleep trial to return it (*plus* a 10-year warranty to boot).
Promising review: "When you’re tall and big, you just don’t take much pleasure out of mattress shopping. Millions of promises re: this bed will be the best that you’ve ever had and maybe for two to three months, it’s good. After that, you start to see a degradation in your sleep quality and your comfort. It’s been almost three years since I first purchased this Tuft & Needle Twin XL (two for one king size bed) and I love this mattress. The shape hasn’t changed. The support hasn’t changed. The comfort is still there. I am a side sleeper. Since COVID, I have spent a few days a week working from my bed and still — nothing has changed in the way of shape, support, or comfort. For a week, I was in bed 20 hours a day while recovering from a back injury. I feel like the comfort and support aspect aided in my recovery period. When and if I have to replace this, I will go with Tuft & Needle again. It’s the first mattress that lived up to all of its promises." —Kristina
