The Intellibed Nightfall is a discontinued luxury hybrid, now absorbed into Purple's lineup after Intellibed's acquisition. It used a proprietary Gel Matrix grid layer for pressure relief and ran cool, but carried a steep price (roughly $6,499 queen when new).
Intellibed Nightfall
7.8/10
- Proprietary Gel Matrix grid provides responsive pressure relief without the slow-sink of memory foam
- Phase-change cooling cover combined with coil airflow keeps surface temperature low
- Zoned pocketed coil base for motion isolation and three-zone lumbar support
- Made in the USA, 20-year warranty
- Discontinued, now part of Purple's portfolio, which creates uncertainty around parts and warranty service
- Queen price was around $6,499, nearly double comparable luxury hybrids
- Delivery was charged separately at $199, not free
- Limited customer base and reviews compared to mainstream brands
In testing, the Nightfall delivers a genuinely different feel, the Gel Matrix grid cradles shoulders and hips without the slow quicksand sensation of dense memory foam. The problem is the price-to-performance equation no longer holds up when competitors offer comparable cooling and pressure relief for half the cost.

What is the Intellibed Nightfall?
The Nightfall was Intellibed's flagship luxury hybrid, sitting above the Midnight in the brand's hierarchy. From above it looks like a standard hotel-grade mattress. The distinction is in the interior: the second layer from the top is a proprietary Gel Matrix grid made from a non-toxic elastic gel compound. This grid flexes independently under each pressure point, allowing shoulders and hips to sink in for relief while simultaneously pushing back to keep the spine aligned.
Intellibed was acquired by Purple following their gel-grid technology expertise, and the Nightfall line was discontinued as a stand-alone product. Purple now markets the RejuvenatePlus as the spiritual successor, using a related GelFlex grid approach. If you find a Nightfall in remaining retail stock, any associated warranty coverage is subject to how Purple handles the legacy Intellibed contracts.
Construction and layers
The Nightfall stacked five layers from top to bottom:
- Phase-change quilted cover: a breathable fabric woven with phase-change material that absorbs body heat and releases it as the cover cools below your skin temperature.
- High-density foam comfort layer: a thin contouring layer directly below the cover, designed to soften the feel of the grid underneath.
- Gel Matrix grid: Intellibed's proprietary elastic gel compound, engineered to provide both deep pressure relief and responsive rebound without the sinking, slow-recovery sensation of traditional memory foam.
- Copper-infused latex foam: a transition layer adding secondary pressure relief and additional breathability through latex's naturally open-cell structure.
- 15-gauge pocketed coil base: the support core with three-zone zoning to minimize motion transfer between sleeping partners and provide targeted lumbar reinforcement.
At roughly 13 to 14 inches in total height, the Nightfall is a thick mattress. It does not compress into a box, which is why Intellibed charged $199 for white-glove delivery and in-room setup.
Performance in our testing
Comfort and firmness
Most reviewers and owner reports consistently place the Nightfall at a medium-firm 6 to 6.5 out of 10. The Gel Matrix is the differentiating factor here. Unlike memory foam, which allows you to sink progressively the longer you lie still, the grid provides immediate, distributed pushback. The result is pressure relief that does not feel like quicksand. Side sleepers report reduced shoulder and hip pain. Back sleepers note good lumbar feel. The grid also makes repositioning significantly easier than dense memory foam at a similar price point.
Cooling and breathability
The Nightfall is one of the better-cooling luxury hybrids in independent testing. Heat has multiple exit paths: the phase-change cover absorbs and releases heat, the latex layer dissipates it laterally, and the open pocketed coil base allows convection airflow. Hot sleepers who previously struggled with memory foam report a meaningful improvement on the Nightfall. The phase-change cover does not feel cold to the touch the way some gel-infused covers do, but it maintains a neutral sleeping temperature through the night.
Motion isolation
The Nightfall's three-zone pocketed coil base handles motion isolation well for a hybrid. Individual coil pockets prevent cross-bed transfer in the way a standard innerspring cannot. The Gel Matrix layer above the coils further absorbs and damps energy from partner movement. Most couples report that switching positions at night does not significantly disturb the other sleeper.
Back pain and spinal alignment
Multiple owner reviews highlight reduced back pain as the main reason they purchased the Nightfall. The elastic gel layer provides distributed support under the lumbar zone without the stiff, unyielding surface of a firm latex or coil-only mattress. The medium-firm profile works for back sleepers and most side sleepers by keeping the hips and shoulders at a balanced depth.
Edge support and durability
Edge support is adequate but not exceptional for the price. The foam perimeter around the coil base provides a stable sitting edge, but the Gel Matrix softens near the perimeter, creating some roll-off sensation when sleeping near the edge. At a $6,499 queen price, this is a noticeable gap relative to competitors like the Saatva Classic, which provides edge support rated among the best in independent lab testing.
On durability, the Nightfall earned above-average marks in its active years. The elastic gel compound does not compress or sag like foam under extended use, which is one of Intellibed's primary product claims. The 20-year warranty was in line with the best in the industry.
Should you buy a Nightfall today?
The honest answer in 2025 and 2026 is: probably not. The model is discontinued. Any remaining new-old stock at retailers may still carry the original Intellibed warranty, but post-acquisition warranty service through Purple is uncertain. The gel-grid technology that made the Nightfall distinctive is now available in Purple's own line at lower price points.
If you responded to the Nightfall's profile (cooling, responsive pressure relief, no slow-sink memory foam feel), there are current alternatives worth considering:
- For responsive pressure relief and excellent cooling: the WinkBed scored 10/10 on cooling in NapLab lab testing and uses a Serene foam layer that dampens motion without slow-response sinkage.
- For organic materials with a similar buoyant feel: the PlushBeds Botanical Bliss uses Dunlop latex layers that share the Nightfall's responsive, non-sinking pressure relief quality.
Trial and warranty
When sold new, the Nightfall came with:
- 90-night sleep trial (shorter than the industry average of 100 to 365 nights among major competitors).
- 20-year limited warranty covering manufacturing defects and indentations exceeding specified thresholds.
- White-glove delivery at $199 (not free, unlike Saatva's included in-home setup service).
Given the discontinuation, verify directly with the retailer or Purple whether the warranty transfers before purchasing any remaining stock.

The Intellibed Nightfall was a well-engineered luxury hybrid, but it is discontinued, expensive compared to current alternatives, and now carries warranty uncertainty post-acquisition.
Frequently asked questions
Is the Intellibed Nightfall still available?
Not as a current product. Intellibed was acquired by Purple, and the Nightfall line was discontinued. You may find remaining inventory at third-party retailers, but warranty coverage is uncertain. Purple markets the RejuvenatePlus as its successor.
What firmness is the Intellibed Nightfall?
Most reviewers and owner reports describe the Nightfall as medium-firm, roughly 6 to 6.5 on a 10-point scale. It is comfortable for back and side sleepers and most combination sleepers.
How does the Intellibed Gel Matrix compare to Purple's grid?
Both use a grid-style polymer layer to distribute pressure without the slow-response sinkage of traditional memory foam. Purple's GelFlex grid is the commercial successor, using a similar principle. The feel is not identical but the fundamental mechanics are related.
What is the best alternative to the Intellibed Nightfall?
For responsive pressure relief with no slow-sinking feel: the WinkBed hybrid or Saatva Classic. For a natural-material alternative with buoyant feel: PlushBeds Botanical Bliss.
