DLX Mattress - Classic Two Sided Mattress

Based on what you’ve described, it sounds like you’re stuck in a bit of a mattress twilight zone, and you’re definitely not alone. Many active people with athletic builds and sensitive lower backs or SI joints struggle to find a mattress that provides proper support without aggravating pressure points. You’ve also correctly identified that a mattress that’s too soft or starts sagging can be just as problematic as one that’s overly firm, especially for side sleepers. Recently, I got one of my daughters the Helix Twilight Luxe. She actually had the chance to try it in a store while I was visiting her on vacation. She initially liked the Midnight in the showroom, but knowing how these mattresses tend to soften a bit after about a month or so, I usually lean toward the next firmness level up. She’s athletic, curvy, 5'3", about 140 pounds, and mainly a side sleeper. While the Midnight felt good in the store, the Twilight ended up being the perfect choice. Initially she said it was a bit firm, but adjusted within about 10 days and is now sleeping comfortably. She also really liked the GlacierSleep Apex, which is what she and the other kids (late 20s to early 30s) sleep on when they’re in the guest room at home. For another daughter, I sent her the DLX Classic Hybrid Medium. It runs a bit softer on the firmness scale, which is good for a guest room mattress as it covers the spectrum of sleepers, but for someone like you, I’d suggest going with the firm version instead. Back to your specific situation, it sounds to me, you would like a mattress with a more robust spring support system to keep your hips and lower back properly aligned. A few options I’d suggest looking into are the Helix Twilight Luxe with ErgoAlign, which offers great support and alignment for athletic side sleepers, the Titan Plus Elite, which has excellent comfort layers for side sleeping, microcoils in the comfort layer to promote cooling airflow, and has a more reinforced support spring core with 13.5gauge springs. It is the firmer support offered by 3Z brand mattresses. The DLX Classic Hybrid Firm, and the GlacierSleep Original, which has a responsive, supportive feel that some active sleepers really like. If you feel like you’re not getting enough push-back or lift from traditional foam or coil hybrids, latex may be a better fit. It doesn’t let you sink in the way memory foam does. Instead, it contours with a buoyant, supportive feel. Some latex hybrid options to consider are My Green Mattress, SleepEZ, Arizona Premium, and Avocado Green. Arizona Premium and Sleepez is especially great if you want custom firmness. They can craft a setup specific to your needs, and you can even swap out latex layers at home to fine-tune the feel if something’s off. These latex hybrids offer zoned or customizable support and are more responsive than memory foam. They help keep your spine aligned while still offering the pressure relief that side sleepers need. I have written a lot about the need or not to test a mattress in the store before purchasing. Most of the better BiBs that are sold through reputable online retailers or independent authorized dealers offer detailed guidance and customer support to help you choose the right model. They often provide better value, clearer transparency about materials and construction, and more generous trial and return policies than what you’ll typically find in big-box showrooms. Returns are costly for these independent authorized dealers, so there is a much greater incentive to fit you with the right mattress right out of the gate. Hope this helps a bit.

I have five mattresses in my house. I sleep on a Plank Luxe. Whenever we go away, whether it's a five-star hotel or not, we always end up sore until we get back home. The Plank Luxe brings us right back to normal. I’m 6'0", 220 lbs, and my wife is 5'4", 135 lbs. So you can throw out the stereotype that only lighter people can side sleep on a firm mattress. Our Titan Plus Elite is another great mattress. It is very comfortable. I tested it at the LVM Mattress Convention last year and was so impressed that I bought one for the guest room. My GlacierSleep Apex is not as firm as the Plank or the Titan Elite, but it is a pleasure to sleep on. It is better than any hotel mattress we have tried, including the Ritz-Carlton in Lower Manhattan, and far better than the mattresses used at the MGM Grand in Las Vegas. I also have two very budget-friendly mattresses that I call my “curiosity mattresses.” These are the Brooklyn Bedding Standard Hybrid and the FlexiSpot U3. Both are surprisingly comfortable, although I am not sure either will hold up for seven to ten years of everyday use. I bought my mother-in-law a DLX Premier Hybrid Firm/Medium split. It feels like a Stearns & Foster Lux Estate but with better components. She has had it for over a year and a half now. It performs flawlessly and ultimately still perfect, like the day it arrived. Before that, her Beautyrest Black lasted only 14 months. I also got my daughter a DLX Classic Hybrid. It is a very comfortable mattress. It is too soft for me personally, although still comfortable. I would have preferred the firm option, but I chose the medium to appeal to a wider range of guests in my daughter’s home. I have tried a variety of Shifman’s firmer mattresses, and I would say they are just about the best out there, right there with ViSpring, Millbrook, Savoir and some other very fine mattresses. I recently bought my other daughter a Helix Twilight Luxe. She loved it in the showroom, so we will see how it performs once it is delivered tomorrow. Helix's new line-up is definitely an improvement over their already decent series of mattresses. Most people come to this sub, and others like The Mattress Underground, to troubleshoot sleep issues. In my experience, the root cause is often the foundation. After that, it usually comes down to a poor match between the sleeper and the mattress. Many shoppers pay more attention to advertising than to the actual materials and construction. Understanding what is inside the mattress and how it fits your body and sleep style is much more important. While specifications do not guarantee comfort, they are the best indicator of durability. If you are shopping for a mattress, start by looking at what it is made of and how well that aligns with your needs, rather than relying on marketing claims.

[DLX classic](https://dlxmattress.com/products/classic-two-sided-mattress) fits the bill. They use a modern pocketed coil and each side of the mattress has regular high density polyurethane foam. Decent mattress for the price. You could also go [Engineered sleep classic hybrid](https://engineeredsleep.com/products/classic-hybrid-mattress). Same story with them except this one runs more on the firmer side, pocketed coils, high density polyfoam layer on each side, their quilting layer is just 1.5pcf density but its a very thin layer of foam so not a huge issue.
