Sealy Clearwater Hybrid
6.8/10
- SealyCool Air gel foam plus transition layer runs cooler than budget all-foam competitors
- StableEdge coil perimeter gives good sitting edge support for the price
- Hybrid construction promotes airflow, good for hot sleepers
- 100-night in-home trial when purchased direct from Sealy
- One firmness only (plush), not ideal for back or stomach sleepers
- 10-year warranty is shorter than most online mattresses at this price
- Non-pocketed coil system transfers more motion than pocketed alternatives
- Limited size pricing transparency outside of Sealy.com direct
The Clearwater is a decent entry-level hybrid for side sleepers who sleep hot. The gel foam layers do keep temperature in check. The trade-off is one firmness level only, moderate motion isolation, and a 10-year warranty ceiling.
Who the Sealy Clearwater is for
The Clearwater is one of Sealy's more accessible hybrid mattresses. Its 11.5-inch profile combines a SealyCool Air gel foam comfort layer, a SealyCool gel foam transition layer, and a ResponsePro innerspring base with StableEdge perimeter reinforcement. That construction makes it genuinely good for side sleepers who sleep hot and want a soft-feeling surface at an entry-level price.
The plush configuration is the only option available. That alone rules out the Clearwater for most back and stomach sleepers, who need firmer support to keep the spine from sagging. If you switch positions during the night, the plushness may not provide enough resistance under the hips when rolling to your back.
The mattress ships in a box and comes with a 100-night sleep trial and a 10-year warranty when purchased directly from Sealy. Both are shorter than what most online-native brands offer at a similar price.
Construction and layers
From top to bottom, the Clearwater stacks as follows:
- Quilted cover: soft knit fabric, wicks some surface moisture
- SealyCool Air gel foam comfort layer: open-cell gel foam designed to dissipate heat faster than standard memory foam
- SealyCool gel foam transition layer: bridges the comfort layer and the coil core, adds stability under pressure
- ResponsePro innerspring base: coil system providing bounce and airflow; StableEdge coil reinforcement around the perimeter
Total height is approximately 11.5 inches. The mattress is not flippable: flipping would put the coil base on top, which is not designed to sleep on. Sealy manufactures in the United States, and the Clearwater ships in a box with standard and expedited delivery options nationwide.
Comfort, support, and performance
Pressure relief
In our testing, the Clearwater provided good pressure relief at the shoulder and hip for side sleepers. The plush foam layers contour without the deep sinkage you feel from a full memory foam bed. For lighter sleepers (under 130 lb), it can also work on the back, but medium-weight and heavy back sleepers will feel the hips sink too far relative to the lumbar.
Motion isolation
Motion isolation is the Clearwater's weakest area. The ResponsePro system uses a traditional coil structure rather than individually wrapped pocketed coils. Movement transfers across the surface more readily. Couples with one partner who tosses at night will notice this. The Clearwater is better suited to single sleepers or couples who are both heavy sleepers.
Temperature and airflow
The Clearwater's strongest performance area is thermal comfort. The combination of an open-cell gel foam top layer, a gel transition layer, and the airflow channels inherent to an innerspring base keeps sleeping temperature lower than you would expect at this price. In our testing, the surface felt noticeably cooler after 30 minutes compared to budget all-foam alternatives.
Edge support
The StableEdge coil perimeter adds meaningful edge support for sitting and for using the full sleep surface. Sinkage when sitting on the edge is moderate. You will not roll off, but the plush top layers do compress under a seated adult.
Durability
Sealy's manufacturing quality is generally reliable. The coil base holds shape well over time. The foam comfort layers are the main variable: plush foams compress faster than firmer ones. A 10-year warranty covers defects and sagging over 1.5 inches. That is standard for the category, though shorter than the 15 to 20-year warranties available on some alternatives.
Price and sizes

Pricing fluctuates at third-party retailers. The 100-night trial and 10-year warranty apply when buying direct from Sealy; retailer terms may differ.
Is the Clearwater adjustable-base compatible?
The Sealy Clearwater is compatible with standard bed frames, foundations, platform bases, and most adjustable base frames. Sealy lists the Clearwater as compatible with adjustable bases on their site. The flexible coil and foam construction articulates without cracking.
Who should skip the Clearwater
- Back and stomach sleepers: the single plush option is too soft to maintain spinal alignment for these positions
- Couples where one partner is a light sleeper: motion transfer from the non-pocketed coil system is noticeable
- Heavier sleepers (200 lb+): the plush foam layers compress faster and may develop body impressions sooner
- Anyone prioritising warranty length: 10 years falls short of what online brands like Amerisleep or Nectar offer
Sealy Clearwater vs. alternatives
The Clearwater competes at the entry level of the hybrid market. Two useful comparisons:
- Sealy Posturepedic Gleam vs. Clearwater: the Gleam steps up to pocketed coils and additional firmness options, better for back sleepers
If budget is the primary constraint and side sleeping is your dominant position, the Clearwater holds up. For anyone who wants a longer warranty, better motion isolation, or firmness flexibility, the step up is worth considering.
The Sealy Clearwater is a capable entry-level hybrid for side sleepers who sleep hot. It runs cool, has decent pressure relief, and ships in a box. The limits are one firmness option, moderate motion transfer, and a 10-year warranty. If you want a longer trial and a more complete support system, see our recommended alternative below.
Our recommended alternative
It uses Bio-Pur open-cell foam (partially plant-based), a HIVE 5-zone layer that firms up under the lumbar, and CertiPUR-US certified materials. The 20-year warranty and 100-night trial are both longer than Sealy's direct offering.
Frequently asked questions
Is the Sealy Clearwater good for back pain?
Only for side sleepers with mild back discomfort. The plush configuration does not provide enough lumbar support for back or stomach sleepers. If back pain is your primary concern, a medium-firm mattress with lumbar zoning is a more appropriate starting point. See our guide to the best mattresses for back pain.
Is the Sealy Clearwater flippable?
No. The Clearwater is a one-sided mattress. The coil base sits at the bottom and is not designed to sleep on. Flipping it is not recommended and will not extend its lifespan.
Does the Sealy Clearwater come in a box?
Yes, the Clearwater ships compressed in a box. Setup involves unboxing, unrolling, and allowing the mattress to expand fully before sleeping on it, typically within a few hours.
What firmness is the Sealy Clearwater?
Plush, which typically falls between 3 and 5 on a 1-to-10 firmness scale. It is designed for side sleepers. There is only one firmness option available for this model.
Is the Sealy Clearwater compatible with an adjustable base?
Yes. Sealy lists the Clearwater as compatible with adjustable bases. The flexible foam and coil construction bends without damage. Verify with your specific base if using a non-standard articulation angle.
