by The Tomorrow Sleep Hybrid was a mid-range pocket-coil hybrid with built-in sleep-tracking technology. It offered a medium/medium-firm feel, strong motion isolation, and decent cooling, making it a solid pick for couples and combo sleepers. The brand was acquired by Serta Simmons Bedding and is no longer sold as a standalone product. If you are shopping for a comparable or better hybrid mattress today, the Saatva Classic is the gold-standard alternative: dual coils, zoned lumbar support, 365-night trial, and lifetime warranty.
Saatva Classic
9.4/10
- Dual coil-on-coil construction with zoned lumbar foam pad for spinal support
- Outstanding edge support and zero off-gassing (ships flat, not compressed)
- Free white-glove delivery, in-room setup, and old-mattress removal
- 365-night home trial and lifetime warranty, with three firmness choices
- Higher price than many bed-in-a-box brands
- $99 return fee applies during the trial period
- Heavier than foam or roll-pack mattresses, not compressible
Where the Tomorrow Sleep Hybrid topped out at a 10-year warranty and a relatively modest coil count, the Saatva Classic layers 884 pocketed coils over a 416-coil base, adds an organic cotton Euro pillow top, and backs it with a lifetime warranty. It is a tangible step up in longevity, lumbar engineering, and long-term value.
Tomorrow Sleep Hybrid Mattress Review (2026)
Tomorrow Sleep launched in 2017 as one of the more ambitious DTC mattress startups: instead of just selling a mattress, it sold a sleep ecosystem. The flagship product was a pocket-coil hybrid paired with an app-connected sleep tracker. The brand built a credible following among tech-forward sleepers before being acquired by Serta Simmons Bedding, one of the largest mattress manufacturers in the United States. As of 2026, Tomorrow Sleep mattresses are no longer sold through the original brand website, and active distribution has ended.
This review covers the Tomorrow Hybrid's actual construction, how it performed during the years it was available, and what to look for today if you are shopping for something comparable. We will also note what the Saatva Classic, our current top pick in the hybrid category, does differently and better.
Construction and Layers
The Tomorrow Hybrid used a layered construction centered on individually pocketed coils:
- Cooling memory foam (top comfort layer): open-cell texture designed to dissipate heat faster than traditional slow-response foam.
- Gel-swirl pressure-relief layer: gel infused into the memory foam to further moderate surface temperature and contour to the shoulders and hips.
- Dynamic response memory foam (transition layer): a medium-firm transitional foam that kept the surface from feeling too slow or too springy.
- Individually pocketed coil system: the core support layer. Coils responded independently to different body zones, reducing motion transfer between sleep partners.
- High-density base foam: the perimeter reinforcement and foundational layer, contributing to edge stability and long-term shape retention.
Total height was 10 inches across all sizes. The mattress was not flippable: the comfort layers are orientation-specific. It shipped compressed in a box, compatible with most bed frames including slatted bases and adjustable foundations.
Firmness and Feel
Tomorrow described the hybrid as medium/medium-firm, which most sleepers felt sat around a 5 to 6 out of 10 on a standard firmness scale. The top foam layers provided an initial hug and body contouring, but the coil system beneath pushed back with more responsiveness than a pure foam mattress. The result was a balanced feel: not as body-conforming as thick memory foam, not as bouncy as a traditional innerspring.
Back sleepers reported solid lumbar support at this firmness. Side sleepers under 180 lbs generally found adequate shoulder and hip pressure relief. Stomach sleepers on the heavier end and sleepers over 230 lbs sometimes found the medium profile insufficient, preferring something firmer with more push-back in the lumbar zone.
Cooling and Breathability
The open-cell and gel-swirl foam layers were Tomorrow's answer to the heat-retention problem common to all-foam mattresses. The coil core provided passive airflow through the mattress body. By most accounts the Tomorrow Hybrid slept neutrally to slightly cool, a meaningful advantage over comparable all-foam options at a similar price point. Hot sleepers who primarily sleep on their back or stomach generally reported the temperature as acceptable. Side sleepers who burrow into the surface occasionally noted some heat buildup overnight.
Motion Isolation and Edge Support
Motion Isolation
Pocketed coils, by design, contain disturbance within each column rather than transmitting it across the surface. The Tomorrow Hybrid's pocket-coil system, reinforced by the foam transition layer, produced above-average motion isolation for a hybrid. Couples with light sleepers found it significantly better than a traditional innerspring at absorbing partner movement.
Edge Support
The high-density perimeter foam gave the Tomorrow Hybrid reasonably firm edge support for sitting or sleeping near the border. It was not exceptional, but it held up well for a compressed box-ship mattress. Taller or heavier sleepers who regularly sleep at the edge of the bed found the perimeter adequate for short-term use, less so as the primary sleeping position over years.
Sleep Technology Integration
The built-in sleep tracker was Tomorrow Sleep's differentiating feature. The system collected data on sleep duration, movement, and breathing patterns and sent it to a companion app. During the brand's operational years, the tracking data offered useful high-level insights for users interested in understanding their sleep patterns without a separate wearable device.
After the Serta Simmons acquisition, the app and tracking ecosystem were discontinued. If you own a Tomorrow Sleep mattress, the tracking functionality no longer operates. For sleep-tracking needs today, dedicated wearables (Oura Ring, Fitbit) or purpose-built smart mattress systems (Eight Sleep, Sleep Number 360) are the active alternatives.

Tomorrow Hybrid: Pros and Cons
- Medium/medium-firm feel suited a wide range of sleep positions and body types
- Better-than-average motion isolation for a hybrid, good for couples
- Gel-swirl and open-cell foam layers kept surface temperature neutral to cool
- Built-in sleep tracking was genuinely useful during the brand's operational life
- 365-night trial was generous for the category in 2017
- Made in the USA with CertiPUR-US certified foams
- Brand discontinued: no longer available for new purchase
- Sleep tracking and app ecosystem are inactive post-acquisition
- 10-year warranty shorter than competitors offering lifetime coverage
- 10-inch profile modest versus the 11.5" to 14.5" options now standard at this price
- Medium feel may not be firm enough for heavy or strict stomach sleepers
Who the Tomorrow Hybrid Was Best For
- Couples: the pocketed coil system with foam isolation layers minimized motion transfer, one of the stronger points of this mattress.
- Tech-interested sleepers: the built-in tracker made sleep monitoring frictionless, no additional hardware required.
- Side and back sleepers under 230 lbs: the medium/medium-firm feel provided good pressure relief and adequate lumbar support for this range.
- Hot sleepers wanting a hybrid: the coil core and gel-swirl foam outperformed all-foam alternatives on temperature regulation.
Who Should Look Elsewhere
- Anyone shopping for a new mattress today: the Tomorrow Sleep brand is discontinued and units are not available through authorized channels.
- Heavier sleepers (230 lbs+) who need a firmer base or thicker coil support.
- Sleepers who prioritize a lifetime warranty: the 10-year coverage was below what many competing hybrids offered.
- Anyone who valued the sleep-tracking feature: the ecosystem is inactive post-acquisition.
What to Buy Instead in 2026
If the Tomorrow Hybrid matched your sleep profile, the features to look for in a current replacement are: a pocket-coil hybrid with at least 800 coils in queen, a true transition foam layer (not just thin batting), cooling-oriented comfort layers, and a trial of at least 100 nights. Below is how the Saatva Classic and Saatva Latex Hybrid compare as the closest current alternatives:
| Mattress | Type | Firmness | Trial | Warranty | Queen price |
|---|---|---|---|---|---|
| Saatva Classic | Dual coil-on-coil hybrid | 3 options (Plush / Lux Firm / Firm) | 365 nights | Lifetime | ~$1,395 |
| Saatva Latex Hybrid | Latex + pocket coils | Medium + Firm | 365 nights | Lifetime | ~$1,895 |
| Tomorrow Hybrid (original) | Pocket coil + memory foam | Medium/medium-firm | 365 nights | 10 years | $1,100-$1,400 (discontinued) |
The Tomorrow Sleep Hybrid was a genuinely well-constructed mattress that combined coil support, foam pressure relief, and a useful sleep-tracking layer. With the brand discontinued, there is no path to purchasing one new. The Saatva Classic is the most comparable current product: dual-coil hybrid with lumbar zoning, a three-firmness lineup, 365-night trial, and a lifetime warranty that the Tomorrow Hybrid could not match.
Saatva Classic
9.4/10
Dual coil-on-coil hybrid with zoned lumbar pad, organic Euro pillow top, three firmness options, 365-night trial, free white-glove delivery, and a lifetime warranty. The most directly comparable option to the Tomorrow Hybrid for side, back, and combo sleepers today.
Frequently Asked Questions
Is the Tomorrow Sleep Hybrid still available to buy?
No. Tomorrow Sleep was acquired by Serta Simmons Bedding, and the brand's mattresses are no longer sold through authorized retailers or the original website. If you find one listed on a third-party marketplace, it is a used unit with no warranty or trial coverage.
What happened to the Tomorrow Sleep app and sleep tracker?
The sleep-tracking technology was part of the Tomorrow Sleep ecosystem. Following the Serta Simmons acquisition, the companion app and cloud tracking services were discontinued. Existing mattresses no longer have functional sleep-tracking capability.
Is the Tomorrow Hybrid mattress flippable?
No. The comfort layers are constructed for one-side use only. Flipping the mattress would put the high-density base layer on top, which is not designed for direct sleep contact.
Can the Tomorrow Hybrid be used with an adjustable base?
Yes, the Tomorrow Hybrid's pocket-coil construction is compatible with adjustable bed frames. The mattress was designed to flex with articulating bases without damaging the coil or foam layers.
What is the best mattress to replace a Tomorrow Sleep Hybrid?
The Saatva Classic is the closest functional replacement: a dual coil-on-coil hybrid with memory foam comfort layers, zoned lumbar reinforcement, and a Euro pillow top. It offers a longer trial (365 nights), a lifetime warranty versus the Tomorrow's 10-year warranty, and three firmness options so you can match the medium/medium-firm feel that made the Tomorrow Hybrid popular.
Did the Tomorrow Sleep Hybrid have fiberglass?
The original Tomorrow Sleep Hybrid used a silica-based fire sock rather than raw fiberglass batting, similar to many mid-range hybrids of that era. The foams were CertiPUR-US certified. If you own one and are concerned about the fire barrier materials, check the original product documentation or contact Serta Simmons directly, as they absorbed the brand's customer records.
