When you invest in a new mattress, you want a product that’s built to last. A high-quality mattress, made from durable materials, will support you and your partner’s body weight for years to come, without showing any obvious signs of wear and tear. A low-quality mattress might exhibit signs of sagging and indentations after the first 12 months, losing more and more of its shape and its stability.
Naturally, most sleepers are going to want the former over the latter. The question is, which online mattress brands will help you ensure a sag-free experience in the long run? In this article, we’ve outlined some high-quality mattresses that we’ve tested and found to be incredibly resilient. All of them come highly recommended by the product testing team at Mattress Advisor in partnership with SPY.
Here are our top picks:
- Saatva — Best Luxury Mattress
- Brooklyn Signature — Best Universal Mattress
- Puffy — Best for Couples
- Nectar — Best Value
- Birch — Best Organic Mattress
- Layla — Best for Pain Relief
- GhostBed — Best for Hot Sleepers
Nobody wants a saggy mattress. The truth is, high-quality, sag-free mattresses can be found across different mattress types, ranging from innerspring mattresses to latex beds and beyond. You can even get a great memory foam bed that’s built for the long haul. Consider different firmness levels and mattress types, but always make durability a high priority.
1. Saatva Mattress
BEST LUXURY OPTION
We love the Saatva mattress because it emanates luxury. The experience begins when the Saatva team brings the mattress to your home and sets it up for you in the room of your choosing. Note that you can select a mattress from three different points on the firmness scale. Outstanding spine alignment makes this a perfect mattress for side sleeping, and the high-quality materials (including quilted euro pillow top and individually wrapped coils) earn it a perfect score in durability.
2. Brooklyn Signature
BEST UNIVERSAL MATTRESS
When shopping for a new bed, it’s always important to choose one that matches your sleeping position. The Brooklyn Signature makes it easy. We find this to be an exemplary universal mattress, meaning it works well for side sleepers, back sleepers, and stomach sleepers alike. It even offers the responsiveness required for combination sleepers (people who toss and turn). Also be aware that this hybrid mattress offers multiple firmness options, and that multiple comfort layers have a cushioning effect on pressure points and sensitive joints.
3. Puffy Mattress
BEST FOR COUPLES
If you share your bed with a partner or even a pet, it’s important to find a mattress that minimizes night time disturbances and disruptions. The Puffy mattress fits the bill; in our testing, we found it to be one of the best options for couples. There’s plenty more to love about the Puffy, as well: Its medium-firm top layer helps relieve back and joint pain and its memory foam construction offers a contouring sensation. Despite being all-foam, it actually resits extreme temperatures pretty well. We recommend this for couples who want a comfy and breathable mattress that won’t start sagging.
4. Nectar Mattress
To stretch your mattress dollar, consider the Nectar, which offers a low price point, generous sleep trial, and the famous Nectar warranty — not to mention our vote for the best memory foam mattress at a reasonable price point. (A queen size mattress costs under $800!) This gel memory foam bed-in-a-box works well for all sleep positions, and its high-density foam provides great motion isolation and pressure relief for couples. We also love it for the way it promotes a healthy, natural posture, helping you to wake up each morning absent of any creaks or stiffness.
5. Birch Mattress
BEST ORGANIC MATTRESS
Looking for an eco-friendly mattress? We love the Birch, a natural latex mattress that’s made with a number of sustainably sourced components, including organic wool and individually wrapped innerspring coils. A reasonably firm mattress, it offers ample comfort, support, and pressure relief. And, in our testing, we found that it did an outstanding job with motion transfer, making it one of our top picks for couples. If you want to shop green and avoid the sagging mattress experience, Birch is the way to go.
6. Layla Mattress
BEST FOR PAIN RELIEF
Do you struggle with lower back pain, joint pain, hip pain, or shoulder pain? If so, we recommend the Layla, a memory foam mattress in which each foam layer is infused with copper. This unique design has anti-inflammatory effects, meaning it can soothe muscles and diminish the effects of arthritis. Also, the Layla has a flippable design, making it easy for you to alternate between a firm mattress and a soft mattress, according to your comfort preferences.
7. GhostBed Mattress
BEST FOR HOT SLEEPERS
Nobody likes waking up with the nighttime sweats. If you tend to run hot in the night, the GhostBed was made with you in mind. We find that its blend of cool latex foam and breathable polyfoam support system helps mediate body heat and regulate sleeping temperature. It ranks well above average in the cooling department, but it’s also noteworthy for having a nice bouncy feel, and for offering full support for sleepers regardless of body type. It’s not an especially expensive mattress, and we’d consider it a good buy for those prioritizing breathability.
