By Jennifer Nelson published 13 July 2022 (Image: © Helix) Tom's Guide Verdict The Helix Midnight is a competitively priced hybrid mattress that delivers the comfort and support of a more expensive model. It's an excellent choice for side sleepers, providing deep pressure relief right exactly you need it. We loved how cool it felt at night too. Watch out for the stitching though, as it's handmade so may not always be picture perfect. Pros + Excellent for side sleepers+ Great pressure relief+ Cool sleeping temperature Cons - Too soft for stomach sleepers - Some irregular stitching on ours- Very heavy in the box on arrival Jump to: What is it?

The brand crafted the Helix Midnight as a mattress for side sleepers and it certainly excels at that. In testing this medium-firm hybrid mattress ourselves, we found it offers excellent pressure relief along your back, hips, and knees. Like many of the best mattresses these days, the Helix Midnight has experienced a price increase due to inflation; however, it still comfortably sits at the lower end of the mid-range mattress tier with a queen retailing for $1,199. There are also regular Helix mattress sales that can knock as much as $150 off the Helix Midnight. The Helix Midnight mattress is made up of four layers; The top three layers comprise Memory Plus foam, Helix dynamic foam and high-grade polyfoam, with a fourth layer of 8-inch individual pocketed coils. All of that is wrapped in a breathable, soft-knit fabric that stays cool to the touch. If you tend to sleep very warm at night and have the budget to upgrade, the Helix Midnight Luxe features an additional copper gel memory foam for pressure relief plus a premium quilted pillow top. We slept on a king-size Helix Midnight mattress for three weeks, following our methodology for mattress testing to thoroughly put it through its paces and help you decide if it'll be right for your sleep needs. If you like the sound of our review, you'll be able to try the Helix Midnight risk-free at home via a 100-night sleep trial - with a full refund and free returns if you're not satisfied. Otherwise, your purchase will be backed by a 10-year warranty (15 years for the Helix Midnight Luxe). Keep reading to learn all about our experience with the Helix Midnight mattress, the brand's best-selling mattress in a box... What is the Helix Midnight mattress Hybrid mattress made from foam and coilsMedium comfort level12 inches deep The Helix Midnight is the company's most popular hybrid mattress. It's a generous 12-inches deep, medium firmness, and designed primarily for side sleepers. (If you're more of a back or stomach sleeper, choose the Helix Dusk (opens in new tab) instead - it's the same medium hybrid mattress, but tailored for back and front sleeping).Helix Midnight: specs (Image credit: Helix Sleep)Best for: side sleepers, couples, hot sleepers Type: hybrid Firmness: 6.5/10 (medium) Materials: foam, springs Depth: 12 inches Weight: 50-110 lbs Sizes: Twin, Twin XL, Full, Queen, King, Cal King Trial length: 100 nights Warranty: 10 years On top, a breathable, stretchy, soft-touch cover is optimized for improved airflow. Inside, meanwhile, the mattress is packed with pressure-relieving materials. First there are two comfort layers, starting with a slab of Helix's bespoke memory plus foam. This relieves pressure, providing soft sinkage and deep body contouring, while cradling pressure points along your shoulders, hips and lower back. It's also more breathable than some of the best memory foam mattresses. Next, a transition layer of responsive high-grade polyfoam provides a little bounce and helps absorb sinkage from the top layer of memory foam, while offering extra cushioning for your body. After that comes a support layer with hundreds of individually wrapped coils: these cradle your body, while also limiting motion transfer and reinforcing edge support around the perimeter. They boost airflow too, helping make the Helix Midnight cooler than an all-foam mattress might be. Finally, a solid base layer lends durability and stability across the mattress. (Image credit: Helix) It's worth noting that no harmful chemicals, ozone depleters, PBDE flame retardants or heavy metals are used in the Helix Midnight mattress – the company prides itself on its OEKO-TEX and Certi-PUR-US certified materials. We explain more about these materials in our best organic mattress guide. Helix is an online-only company, so you can't try the Midnight in-store. Instead, it comes with a 100-night sleep trial, so you can make sure it's the right fit by actually sleeping on it. This is far more effective method than five minutes in a showroom. The Helix Midnight mattress comes shipped direct to your door, rolled up and vacuum sealed inside a conveniently sized box. If you're unhappy with it for any reason, you can return it for a refund within the 100-night trial period, after the 30-day 'break-in period' has passed. The Helix Midnight mattress also comes with a 10-year warranty. When we received us for review, we found it incredibly heavy to bring inside and into our bedroom for testing.

The Helix Midnight is a straight-down-the-line solution for side sleepers who want a medium-feel mattress, or if you're not sure which of Helix's mattress is the best fit for you, then this is a good starting point too. How much does the Helix Midnight mattress cost? It starts at a great price, from $799, but keep an eye out for offers – our guide to the best Helix mattress sales and deals contains the latest savings. There's plenty to choose from across the entire Helix range, so if you wanted to upgrade the Helix Midnight mattress to include a plush top and even more support, then the Midnight Luxe is a better choice. It will set you back a few hundred dollars extra though, with a starting price of $1,199. Back to the standard Helix Midnight, during our review period we were pleased to report that it felt supportive during sleep from the start. It's cozy to the touch, and comes with adequate bounce, but also delivers enough firmness and excellent pressure relief across the entire body. (Image credit: Helix) Our reviewers were happiest sleeping on their sides when reviewing the Helix Midnight mattress, as well as on their backs, being perfectly comfortable with pressure points well-cushioned and cradled by memory foam. However, we think stomach sleepers might prefer the firmer Helix Twilight (opens in new tab) or the Helix Dawn (opens in new tab) instead. The temperature of the Helix Midnight mattress was particularly impressive, and none of our reviewers felt overheated during sleep. The hybrid construction features an 8-inch layer of coils that allows for decent airflow, while the breathable cover keeps the surface cool to the touch. During our review, we also noticed how silent the Helix Midnight is in use, with no noise from the coils. Even better, there was little in the way of motion transfer, making it a good choice for restless sleepers and couples with different sleep schedules. There was little to complain about with the Helix Midnight mattress, although because it's handmade, you may notice a few irregularities, such as slightly bunched-up stitching here and there. Whether you feel that adds charm is down to you, but it in no way affects the performance of the Midnight. When it came to edge support, it was fine for sleeping, although if you sit on the edge of the bed for extended periods of time then you might start to slope off a little. The Helix Midnight mattress comes with a 10-year warranty, a 100-night sleep trial and free shipping for all orders within the US. If after at least 30 days you decide the mattress isn't for you, then Helix will arrange for it to be collected and they will do their best to donate the mattress to a local charity or recycling center.

Considering this is an affordable mattress anyway, that's excellent value for money.View Deal (opens in new tab) Helix Midnight mattress price and dealsGood value, mid-range mattressCheaper than CasperFrequent sales reduce the price further The Helix Midnight sits at the lower end of the mid-range mattress market. At full price, it costs between $799 for a twin size and $1,549 for a Cal king. Although that's a $100 increase across the board (due to inflation), those are still competitive prices for a hybrid bed-in-a-box, which is typically pricier than all-foam options. A queen Helix Midnight hybrid retails for $1,199. That's well under the costs of its queen-sized hybrid rivals: the Casper Original ($1,695), the DreamCloud mattress ($1,798), and the luxury hybrid Saatva Classic mattress ($1,770). It's even $200 less than the foam-and-grid Purple mattress ($1,399). Here's the official pricing for all sizes:Twin: $799Twin XL: $899Full: $1,049Queen: $1,199King: $1,549California King: $1,549 However, there are frequently Helix mattress deals that cut between $100-$200 off the price of the Helix Midnight mattress – and you'll often get two free pillows added to your order too. Typically these offers run during the Black Friday mattress deals bonanza, Memorial Day, the July 4th sales, and on Labor Day, but you'll find plenty of offers happening between those events too. If you don't immediately see a discount, it probably won't be long until the next sale launches.

But it's still extremely heavy for one person to move, so we tipped our delivery person to help us carry the box into the right room. It was then fairly easy to unpack and unroll the mattress with two people. Helix says the Midnight needs 30-45 minutes to unwind and fully expand, and our mattress fell within that bracket - just - taking 45 minutes to reach its full dimensions. We heard a slight wheezing as the vacuum seal released, but there was no noticeable off-gassing or odor from the packaging or mattress (although some users have reported a light off-gassing that dissipates within a few hours). Helix classifies the Midnight as between 5 and 6 (medium) on the firmness scale, with 10 as the firmest. The company describes it as "pretty much smack in the middle - not too soft, not too firm" and we'd just about agree, categorizing it as 6.5. It's deceptively soft at first - cushy with a little bounce; but when you lie down it feels surprisingly firm. Bear in mind that firmness is subjective, though. Your exact experience will vary depending on your height, weight and other personal factors. (Image credit: Helix) We gave the Helix Midnight mattress a thumbs up in most areas. Both our reviewers were comfortable from the first night and found the mattress to be genuinely supportive. It's plush to the touch, and a little bouncier than we expected, but it's also firmer than it initially appears, and we found that it delivered deep pressure relief. Helix says the Midnight is best for side sleeping, and that tallies with our experience. Both our reviewers found sleeping on their backs and sides to be extremely comfortable - even cozy. Pressure points including lower back, knees and shoulders were well-cushioned and felt cradled by the foam. For extra pressure relief, consider partnering it with one of the best mattress toppers for your bed. However, one reviewer did feel the mattress wasn't quite as supportive as they'd typically prefer (our other reviewer had no complaints). Some stomach sleepers will likely find the Midnight too plush, as well. If you're a fan of a firmer mattress, take a look at the Helix Twilight (opens in new tab) or Helix Dawn (opens in new tab) mattresses instead. One area where we were particularly impressed with the Helix Midnight is its temperature control. During our two-week test period, the mattress never felt too warm, or caused us to overheat. The breathable cover and airflow through the coils kept us at a cool, comfortable temperature throughout the night - even somewhat alleviating one of the reviewer's "hot sleeping" issue. The mattress also didn't make any noise - there was no creaking from the coils - and had very little motion transfer, making the Midnight a good choice for anyone with a restless partner. Helix midnight mattress what we didn t like (Image credit: Helix)Some irregular stitching on one sideEdge support could be sturdier We couldn't find much to err over with this comfortable mattress, although it's worth being aware that Helix mattress dimensions can vary by up to one-inch on either side because all the company's mattresses are handmade. This didn't cause any performance issues with our Helix Midnight review mattress, but as a minor cosmetic complaint, we did notice an area of irregular stitching on one of the sides. There were 12 inches of bunched-up fabric that weren't as smooth as the three other sides. We also felt that edge support - while adequate - could be marginally better for sitting on the side of the bed for longer periods of time. For sleeping, though, edge support was fine. We don't have any complaints about sagging edges or rolling off while we slept. Helix Midnight mattress user reviews We highly rate the Helix Midnight mattress, but mattresses are subjective - you'll have a different experience depending on your height, weight, sleeping style and a range of other factors. So to build a more rounded picture of what this mattress is like to sleep on, we researched hundreds of user reviews online to see what other people say about the Helix Midnight. On the Helix website, the Midnight mattress has an average of 4.5 out of 5 stars from over 3,000 user reviews (May 2021) - with over 2,000 five-star reviews. Many commented that the mattress "helped with shoulder pain", "relieved lower back pain" and "cushioned pressure points". Some said it's "perfect for side sleepers," and lots agreed that the Helix Midnight mattress is great value. We also checked out a handful of reviews at Consumer Affairs. Most of these didn't specify which Helix mattress they were referring to, but the reviews were largely five-star. Of all the reviews we saw that gave the mattress a lower score, being too soft was the number one complaint. Many exchanged it hassle-free for a different Helix mattress, such as the Twilight. Another user reported that they didn't find it firm enough, so Helix sent them a mattress topper free of charge, which helped. (These mixed responses illustrate, again, that firmness is subjective. We recommend taking the Helix Sleep quiz (opens in new tab) before purchasing a Helix mattress to increase your chances of choosing the right one.) Meanwhile shipping delays and delivery problems were usually cited for the smaller amount of more negative reviews. Should you buy the Helix Midnight mattress (Image credit: Helix) If you sleep on your side or are prone to sweating overnight, the Helix Midnight is one of the best mattresses you can sleep on. Couple will also want to give it some consideration due to its slight bounce and low motion transfer. Best of all, the Helix Midnight is one of the most affordable mattresses-in-a-box out there, undercutting many of its rivals. For stomach sleepers or individuals who weigh over 300 pounds, the medium firmness of the Helix Midnight probably won't cut it for you. We'd recommend the Helix Twilight (opens in new tab) instead, with its no-sink-or-give top layer, or the Helix Dawn (opens in new tab), which comes with extra support for back and stomach sleepers. Both mattresses cost the same as the Helix Midnight. Alternatively, if you have a higher budget, consider the Helix Midnight Luxe (opens in new tab), which starts from $1,195. This is the premium version of the Midnight, with zoned lumbar support, enhanced contouring, a quilted pillow and other luxury features. Otherwise, we thoroughly recommend the Helix Midnight mattress: it's a comfortable, cozy and supportive mattress straight out of the box. To keep it cleaner for longer, invest in one of the best mattress protectors for keeping stains, spills and bugs at bay.
