If your mattress can't handle a bowling ball and a full glass of wine at the same time, how's it going to handle your marriage? This is your traditional spring unit. Call it a Bonnell, an LFK, a continuous coil — they're all linked spring units, and they have a lot of motion transfer. Watch when I drop this bowling ball. Boom, there you go. See how it's super bouncy? It's all connected, everything falls over. That's what a traditional coil will do. Our Diamond-made, individually wrapped coils sit inside individual pockets, which provides motion separation so you can sleep undisturbed. Even if your partner's tossing and turning at night, you don't get all the movement you get in a traditional spring unit. I can even push right here by the wine glass and it's not going to fall over, because these coils are individual. You also get personalized contouring. If your body's a different shape than your partner's, it gives you support where you need it most. If you have more weight in one area, it gives you more support where you need it. It rises up to meet you in the gaps in your lower back — better back support, better contouring, better pressure relief, and motion separation so you sleep soundly all night long. And this is what it looks like in a whole mattress. Those coils create motion separation, so you don't feel movement in your mattress and you can sleep soundly all night long.

Please tell me you're still not sleeping on this. Terrible edge support. Feels like you're going to roll off the bed. Let's get something better. This has great steel edge support all down the sides. I can feel the extra support right under my legs. I feel supported. I can sleep closer to the edge of the mattress without rolling off. And now to my favorite: foam-encased edge support. These rails — so much support. You can feel the coils inside the rails, so they react to you independently and give you incredible edge support. You can sleep all the way to the edge of the bed, use the entire mattress, and never feel like you're going to roll off. No edge support. Good, solid edge support. Amazing foam-encased edge support.

Ever get into a mattress and feel a dip or a soft spot? Your mattress shouldn't do that. A mattress gets that dip or soft spot often because it uses low-density foams. At Diamond Mattress, we prevent that by giving you high-density foams. Think of it like a bag full of balloons. With big balloons — like low-density foam's big cells — if one pops, the bag starts compressing over time and gets soft and empty. With lots of tiny balloons, if one cell pops, you're not going to notice the difference. That's why Diamond Mattress can offer a 20-year warranty, while most brands offer a 10-year warranty. These two blocks are the same size, but one weighs about 50% more than the other. I can prove it on our scale. You'll notice this block is much lighter than our standard Diamond Mattress foams. What's that doing for you? It's giving you lasting comfort, so your mattress feels the same as the day you bought it for a lot longer. Better support, better pressure relief, more comfort, longer lasting. That's why when you buy a Diamond Mattress, you can count on it lasting — and we offer a 20-year warranty to support it.
