Seahorse Diamond Mattress
The Seahorse Diamond Mattress features a unique dual-sided design with different firmness levels on each side. This mattress uses high-density foam layers and advanced construction techniques to provide customizable comfort.
Dual-Sided Design Explained
The Seahorse Diamond Mattress offers two distinct sleeping surfaces in one product. One side provides a medium-firm feel while the other delivers a firmer sleeping experience.
Users can flip the mattress to switch between comfort levels. This design allows couples with different preferences to find their ideal firmness. The dual-sided approach also extends the mattress lifespan by distributing wear across both surfaces.
Each side features different foam densities and arrangements. The medium-firm side uses softer foam layers near the surface. The firm side places denser materials closer to the top for increased support.
The mattress requires regular rotation and occasional flipping. This maintenance keeps both sides in good condition and prevents permanent indentations.
Material and Construction Details
The seahorse diamond mattress incorporates multiple layers of high-density foam. These materials provide durability and consistent support across the entire surface.
The core contains high-density polyfoam that forms the mattress foundation. This base layer maintains structural integrity and prevents sagging over time. The density typically ranges from 1.8 to 2.0 pounds per cubic foot.
Comfort layers use various foam types depending on the side. Memory foam appears in some configurations to provide pressure relief. Polyfoam layers add responsiveness and breathability.
The cover features a removable and washable fabric exterior. This protective layer allows air circulation while keeping internal materials clean. Reinforced edges prevent premature wear along the mattress perimeter.
Comfort and Support Experience
The medium-firm side offers balanced support for most sleep positions. Back and stomach sleepers typically find adequate spinal alignment on this surface. Side sleepers may experience some pressure point relief in the hip and shoulder areas.
The firm side provides enhanced support for heavier individuals. This surface maintains proper spine positioning for back sleepers. Stomach sleepers benefit from the reduced sinkage that prevents lower back strain.
Motion transfer varies between the two sides. The firmer surface transmits more movement between sleep partners. The medium-firm side absorbs motion better due to softer foam layers.
Temperature regulation remains consistent across both surfaces. The high-density foam construction allows reasonable airflow. However, some users may experience warmth retention compared to innerspring mattresses.
Edge support performs adequately on both sides. The reinforced perimeter maintains stability when sitting or sleeping near the mattress edge.
Comfort and Firmness Levels
The Seahorse mattress provides a medium-firm feel that works well for most sleepers. The high-density foam construction delivers solid support while still offering good pressure relief.
Firmness Options for Different Sleepers
The Seahorse mattress rates about 6-7 out of 10 on the firmness scale. This puts it in the medium-firm range that most people find comfortable.
Side sleepers weighing 130-230 pounds get good pressure relief at the hips and shoulders. The foam layers contour enough to reduce pressure points without letting the body sink too deep.
Back sleepers find the firmness level keeps their spine in proper alignment. The mattress provides enough support to prevent the lower back from sagging.
Stomach sleepers who weigh over 200 pounds may find it slightly too soft. Lighter stomach sleepers usually get adequate support to keep their hips from sinking.
The high-density foam base layer prevents excessive sinkage for heavier sleepers. People over 250 pounds still get good support without feeling stuck in the mattress.
Spinal Alignment and Support
The Seahorse mattress uses multiple foam layers to support proper spinal alignment. The top comfort layer provides initial pressure relief while deeper layers offer firmer support.
The high-density foam base makes up about 6 inches of the mattress. This dense layer prevents the spine from bending unnaturally during sleep.
Back sleepers maintain their spine’s natural S-curve on this mattress. The medium-firm feel keeps the lower back supported without creating pressure points.
Side sleepers get good hip and shoulder contouring. The foam allows these heavier body parts to sink slightly while keeping the spine straight.
The mattress responds well to different body weights. Lighter sleepers don’t sink too deep, while heavier sleepers still get adequate support.
Suitability for Various Sleeping Positions
Back sleepers rate this mattress highly for comfort and support. The medium-firm feel prevents lower back pain while providing good pressure relief.
Side sleepers find decent comfort, especially those in the 130-200 pound range. The foam layers provide enough contouring for pressure relief at key points.
Combination sleepers can move between positions without feeling stuck. The responsive foam makes it easy to change positions during the night.
Stomach sleepers get mixed results depending on their weight. Lighter stomach sleepers usually find adequate support to keep their spine aligned.
The mattress works best for people who sleep primarily on their back or side. Pure stomach sleepers might prefer a firmer option for better spinal alignment.
Performance and Durability
The Seahorse mattress delivers solid performance across key areas that matter for sleep quality. Its construction supports good durability, motion isolation, and temperature control for most sleepers.
Durability and Lifespan
The Seahorse mattress uses high-density foam layers that resist sagging over time. The base support layer measures 8 inches of 1.8 PCF foam, which provides strong structural integrity.
Most owners report minimal indentations after two years of regular use. The mattress maintains its shape and support well compared to other online foam brands.
Key durability features:
- High-density support foam
- Reinforced edge construction
- 10-year limited warranty coverage
The foam shows good resilience during compression tests. Edge support remains firm even with regular sitting and sleeping near the perimeter.
Temperature changes don’t appear to affect the foam’s performance significantly. The materials maintain consistent support in both warm and cool bedroom conditions.
Expected lifespan ranges from 7-9 years with proper care and rotation. Heavier sleepers may see slightly reduced longevity due to increased compression over time.
Motion Isolation
The Seahorse mattress performs well at reducing motion transfer between sleeping partners. The memory foam top layer absorbs movement effectively.
Partners report minimal disturbance when one person gets in or out of bed. Rolling over during sleep creates little to no motion on the other side.
Motion isolation ratings:
- Partner movement: Excellent
- Edge movement: Good
- Getting in/out of bed: Very good
The 3-inch memory foam comfort layer handles most motion before it reaches the support layers. This design works better than traditional innerspring mattresses for motion control.
Couples with different sleep schedules benefit from this feature. Light sleepers experience fewer wake-ups from partner movement throughout the night.
The foam’s medium-firm feel contributes to motion isolation without creating a sinking sensation. Movement gets absorbed rather than transmitted across the surface.
Temperature Regulation
The Seahorse mattress includes cooling features to address heat retention common in memory foam. The cover uses breathable fabric that allows air circulation.
Gel-infused memory foam in the top layer helps draw heat away from the body. Small perforations in the foam create additional airflow channels.
Temperature control features:
- Gel-infused memory foam
- Breathable knit cover
- Ventilated foam layers
Most sleepers find the mattress sleeps cooler than traditional memory foam. Hot sleepers may still experience some warmth retention during summer months.
The mattress works best in rooms kept between 65-70°F. Using breathable sheets and maintaining good bedroom ventilation improves temperature regulation.
Side sleepers typically experience better cooling than back or stomach sleepers due to reduced body contact area.
Seahorse Mattress Models Compared
Seahorse offers two main mattress models with different foam compositions and support levels. The Crystal Foam uses high-density memory foam while the Everlasting features hybrid construction with coils.
Seahorse Crystal Foam Mattress
The Crystal Foam mattress uses three layers of high-density foam for support and comfort. The top layer contains gel-infused memory foam that helps regulate temperature during sleep.
The middle layer provides transition support with medium-density foam. This layer prevents sleepers from sinking too deep into the mattress. The bottom layer uses firm support foam to maintain proper spinal alignment.
Key Features:
- 10-inch total thickness
- Gel-infused memory foam top layer
- Medium-firm feel rating of 6/10
- Motion isolation for couples
- 365-night sleep trial
The mattress works well for side sleepers and people who prefer memory foam. It compresses under body weight to relieve pressure points. The gel infusion helps reduce heat buildup common with traditional memory foam.
Seahorse Everlasting Mattress
The Everlasting mattress combines foam layers with individually wrapped coils for hybrid support. This design offers more bounce and airflow than the Crystal Foam model.
The comfort layer uses latex foam instead of memory foam. Latex provides responsive support that bounces back quickly when pressure is removed. The coil system has over 800 individually wrapped springs.
Construction Details:
- 12-inch total thickness
- Latex comfort layer
- High-density foam transition layer
- Individually wrapped coil system
- Reinforced edge support
This mattress suits back and stomach sleepers who need firmer support. The coils provide better temperature regulation than all-foam designs. Edge support remains strong for sitting or sleeping near the mattress perimeter.
Comparison with Other Mattress Brands
Seahorse mattresses cost less than premium brands like Tempur-Pedic or Saatva. The Crystal Foam model competes with Nectar and Tuft & Needle in the memory foam category.
The build quality matches other online mattress companies. Seahorse uses CertiPUR-US certified foams without harmful chemicals. The 365-night trial period exceeds most competitors who offer 90-100 nights.
Price Comparison (Queen Size):
- Seahorse Crystal Foam: $899
- Nectar: $1,198
- Purple: $1,299
