Sweetnight SenseSync Adjustable Bed Base, CoolNest Ultra Memory Foam Mattress & Cooling Memory Foam Pillow 2-Pack Review: Individually, They’re Good, Together They’re Great

Modern bedrooms serve as versatile spaces for sleeping, relaxing, and working, so an adaptable, ergonomic setup is essential for both restorative rest and daily productivity. Pairing the SenseSync Adjustable Bed Base (Queen) with the pressure-relieving, temperature-regulating CoolNest Ultra Memory 14″ Foam Mattress (Queen) and Cooling Memory Foam Pillow (King) creates a tailored space for full-body support—whether you’re relaxing, working, or sleeping. SweetNight sent me all three items to test, and this review will cover them in two parts, starting with the SenseSync Adjustable Bed Base.

What Is It?

Design and Features

Key features and specifications of the SenseSync base include:

1. Positioning and Presets

• Independent Head and Foot Adjustment: Dual motors allow you to elevate your head/back and legs independently.
• One-Touch Presets: Includes convenient remote-controlled settings like Zero Gravity (which elevates the legs above the heart to relieve pressure), Anti-Snore, and a Flat return button.

2. Comfort and Convenience Features

• 3-Level Massage Mode: Gentle head and foot vibration modes with auto-shutoff timers.
• Under-Bed Lighting: Built-in LED lighting to help you navigate the room at night.
• Built-in USB Ports: Convenient USB-A and USB-C charging ports located on the side of the base.
• Child Lock: A safety feature to prevent accidental adjustments.

3. Build and Engineering

• Dual Motor Precision Drive: Independent back and leg motors enable precise adjustments. Stable movement ensures consistent adjustment across positions.
• Low-Noise Operation: Powered by motors engineered to run quietly (under 50 dB).
• Zero-Gap Stability Structure: Designed to minimize shifting, wobbling, and gap separation during movement.
• Flexible Installation: Can be used standalone on its own adjustable legs, placed directly on the floor/platform (zero-clearance), or fitted inside existing compatible bed frames.

The SenseSync Adjustable Bed Base has a foldable, pre-assembled design which makes setup quick and easy. The base unfolds like a ping-pong table.

From there, I just had to attach the legs, flip it over, attach the mattress retainer bar, and plug in the power source.

The legs come in 3″ segments, which allows you to adjust the height from 3 to 12 inches. I chose 12 inches because I like to have room to store things under my bed. As stated earlier, you can also place the base directly on the floor/platform (zero-clearance) or fit it inside existing compatible bed frames.

Compatibility Note:

SweetNight explicitly designs the SenseSync base to pair with 12-inch or 14-inch all-foam memory foam mattresses rather than heavy hybrid or innerspring coils, ensuring the mattress can bend smoothly along the folding hinges without stressing the mechanics.

Once set up, the base is incredibly sturdy. I like that it has a set of legs in the middle to provide even more stability. It’s also pretty heavy, weighing around 138 lbs. So, if you have it up against a wall or in a corner, as I do, I highly recommend putting furniture sliders under the legs. This makes it very easy to move around when making the bed or changing sheets.

The base is controlled with a backlit, candy-bar-style remote. The blue backlight makes it easy to use in a darkened room. The remote allows you to independently adjust the head and foot positions, or you can choose from four one-touch presets:

• TV – One touch brings you to a preset viewing position, so you can sit back and enjoy your favorite shows with ease.
• Anti-Snore – Adjusts your sleeping position to keep airways open for easier breathing, reducing snoring and sleep disturbances.
• Zero-Gravity – Positions your body in a neutral posture to ease back pressure and improve leg circulation after a long day.
• Flat – Returns the base to the Flat position.

Two memory buttons allow you to program your favorite positions. The remote also has buttons for the under-bed LED light and the 3-level back and leg massage. For safety, the remote has a Child Lock that prevents accidental adjustments and keeps the bed controls safely locked when needed.

Performance

Performance-wise, I couldn’t be happier with the SenseSync Adjustable Bed Base (Queen size). It’s easy to set up, has solid build quality, and operates whisper-quiet and buttery smooth.

I also love how versatile the base is. My bed isn’t just for sleeping anymore. I can also use it for work, relaxation, or just lounging around simply with the push of a button on the remote.

I suffer from poor circulation in my legs, and having the ability to raise them while sitting or lying in the bed is a game changer for me. And using the preset TV mode is far better than piling a bunch of pillows behind my back.

I also appreciate the little extras like the under-bed LED lighting and the USB charging ports. Because one can never have too many charging ports. However, one feature I didn’t think I would use much has actually become my favorite: the built-in back and leg massage. The massage has 3 levels and can be operated separately or simultaneously. The massage function is more vibration than deep massage, but it’s still very relaxing. I use it almost nightly as I fall asleep. With a 30-minute auto-off function, I can drift off without worrying about it.

As the second part of the complete sleep setup, SweetNight sent me their queen-size CoolNest Ultra Memory Foam 14″ Mattress along with their Cooling Memory Foam Pillow 2-Pack.

What Is It?

The CoolNest Ultra Cooling Memory Foam Mattress features an advanced 5-stage cooling system, an ice silk cover, and 7-zone ergonomic support to relieve pressure. The Cooling Memory Foam Pillow 2-Pack includes two adjustable bed pillows for hot sleepers, with a dual-sided cover and pressure-relieving memory foam.

Up first is the CoolNest Ultra Cooling Memory Foam Mattress.

Design and Features

The SweetNight CoolNest Ultra Memory Foam Mattress features key technologies designed to keep hot sleepers cool while providing ergonomic body alignment:

1. Advanced 5-Stage Cooling System (Up to 11° Cooler)

• Gradient Cooling Ice Silk Cover: Cool-to-the-touch cover featuring a high Q-Max cooling value (0.25) and over 10,000 micro-pores/cm² for maximum surface heat dissipation.
• PCMflux High-Resilience Foam: Infused with Phase Change Materials (PCM) that actively absorb excess heat and release it as body temperature fluctuates.
• AirMesh Breathable Memory Foam: Features an open-cell, mesh-inspired structure that speeds 3D airflow.
• Ventilated Gel Memory Foam: Formulated with 30% gel infusion and 700+ ventilation holes to draw heat away from pressure points.
• Continuous 3D Airflow Base: Air channels and wavy-cut foam work together to prevent heat from getting trapped in the core.

2. Ergonomic 7-Zone Support

• Targeted Pressure Relief: A wavy-cut ergonomic layer provides varied levels of resistance across 7 distinct body zones (head, shoulders, back, waist, hips, legs, and feet).
• Spinal Alignment: Relieves pressure on shoulders and hips for side sleepers while preventing excessive sinkage at the midsection.
• Endorsed by ACA: Endorsed by the American Chiropractic Association for promoting natural spinal posture.

 3. Motion Isolation & Foundation Stability

• Low Motion Transfer: Dense, multi-layer memory foam absorbs movement from partners or pets.
• Anti-Slip Dotted Base Fabric: Keeps the Mattress firmly anchored on slatted bases, platform beds, or adjustable bed frames.

I’m a combination sleeper, which means I change sleeping positions multiple times throughout the night. I usually start off on my back and end up on my side. My previous memory foam mattress was good, but it was a little firm, which led to shoulder pain and numbness in my arms. One of the main reasons I chose to review the CoolNest Ultra was that it was considered a medium/plush mattress, and I hoped it would help with my issues.

The CoolNest Ultra arrived in a large box, rolled up and vacuum-sealed. Setting it up is four easy steps: unbox, unwrap, position, and let it expand. I positioned it onto the SenseSync Adjustable Bed Base so it could expand properly. The mattress expanded pretty quickly once I removed the packaging. SweetNight says to allow 72 hours for full expansion; however, you can sleep on it after 4-6 hours. I let the mattress expand 10 1/2 hours before using it.

The Sleep Experience

At the time of writing this review, I have been sleeping on the CoolNest Ultra Memory Foam Queen Mattress for about two weeks, and I couldn’t be happier. The experience has been great from the first time I laid down on it. It contours nicely without feeling like you are sinking too much. It does a great job relieving pressure on my back and my biggest problem area, my shoulders. The mattress cradles you, and you can feel the ergonomic 7-zone design adapt to different areas of your body, helping distribute pressure evenly. Sleeping on my side is much more comfortable now, and most importantly, I’m no longer waking up with sore shoulders and numb arms. Thank you, SweetNight!

As for the cooling experience: My French Bulldog, Cooper, sleeps with me in my bed, so I use a protective mattress cover. SweetNight recommends that if you have pets that sleep with you, use one to protect the ice-silk cover from damage from their nails. I reached out to SweetNight support to ask whether using a mattress cover would hinder the mattress’s cooling feature. Here’s a snippet from their response:

… using a mattress protector and fitted sheet can somewhat reduce the direct cooling sensation, since they create a layer between your skin and the ice-silk surface. To help you get the best cooling experience, here are two suggestions: Pre-cool the room: Turn on the air conditioning 20-30 minutes before bed and lower the room temperature to your comfort level. Maintaining a suitable temperature difference will help the fabric’s heat-conducting effect work fully. Choose thin, breathable bedding: Thick or heavy bedding will block heat conduction and weaken the cooling effect, so lighter, breathable options are recommended.

So, bottom line, the less there is between you and the ice-silk cover, the better. That said, I took a short 30-minute catnap on the mattress before putting on my mattress protector and fitted sheet. The ice-silk cover definitely lives up to its name: it is immediately cold to the touch, and the fabric is very soft and comfortable against your skin. But even with the mattress protector on, I still slept cool. I haven’t woken up sweating or hot once.

The only thing I miss about having the protective cover on is that immediately cool-to-the-touch sensation. And I’m glad I have that mattress cover because on the second night, Cooper vomited in the bed. Without that cover, it would have been a disaster. Although cleaning up that mess at 3 in the morning was no fun either.

If you’re skeptical about buying a mattress online, SweetNight offers peace of mind with its 100-night risk-free trial. Essentially, it means you can sleep on the mattress for up to 100 nights. If you’re unhappy for any reason, SweetNight will pick up the mattress at no charge and refund the full purchase price.

Final verdict on the CoolNest Ultra Memory Foam Mattress. It’s an incredibly comfortable mattress that softly cradles your body but still gives it the support it needs. And if you sleep warm, the Advanced 5-Stage Cooling System will give you a cool, restful night’s sleep, even if you need a protective mattress cover.

Next is the last piece of this complete sleep setup: the Cooling Memory Foam Pillow 2-Pack.

Top features of the Cooling Memory Foam Pillow 2-Pack:

• Cool-to-the-Touch, Breathable Design
• Customizable Support for Every Sleep Position
• Neck & Shoulder Pressure Relief

The pillows come packaged like the mattress, rolled up and vacuum-sealed. They also come with a removable cover. This cover has two sides, each with a different texture. One side is a Temp-Balanced Fabric. This fabric is made from plant-based fiber and engineered to maintain an ideal temperature. Side two is an Ultra Cooling Fabric – IceBloom-Shape 3D weaving. Like the ice-silk cover on the mattress, the material feels cool to the touch and pulls heat away for a cooler sleep experience.

The outer pillowcase has a zipper closure, making it easy to remove for cleaning. It’s also machine washable. A 2-inch mesh edge around the cover also promotes airflow.

Most memory foam pillows use a solid piece of memory foam. The SweetNight Memory Foam pillow is filled with a 50/50 blend of shredded memory foam and down alternative. This provides better ventilation and a slower rebound for neck comfort. You can also add or remove fill to customize the size that feels best to you.

SweetNight recommends letting the pillows expand for 24-48 hours before using. Since I already had pillows to use, I let them expand for 72 hours to be sure. I also occasionally fluffed the pillows to make sure they expanded fully. The pic below shows before and after.

Night, Night

Like the CoolNest Ultra Memory Foam Mattress, the Cooling Memory Foam Pillow felt comfortable right away. It provided great comfort and support for both my head and neck, whether I was lying on my back or side. The pillow is the perfect height for me, and I wake up pain-free every morning. Although the pillow is perfectly stuffed, I wish it had a little extra fill in case I need it later. I reached out to SweetNight to ask whether extra fill was available for purchase, but it wasn’t. Although I have a queen-size mattress, I chose king-size pillows because I like the extra real estate they provide.

Together, the Cool-Touch cover, shredded memory foam fill, and mesh edge create a nice, cool sleep experience. I slept on each side of the pillow. Although the Cool-Touch side is much cooler at first, both sides provided a similar overnight experience. I never woke up hot or having to search the pillow for a cool spot. Ultimately, the Cooling Memory Foam Pillow provided an extremely comfortable night’s sleep, and that’s no small thing.

Final Thoughts

Each of these SweetNight products is very good on its own, and I would recommend them all, but together they’re great. Each piece plays off the others and creates an extremely enjoyable user experience. They give you the cool, restful sleep you deserve. I like them so much that I’m looking to purchase one of SweetNight’s bed frames and take advantage of the SenseSync Bed base’s zero-clearance feature. So, whether you’re in the market for one or all of these products, do yourself a favor and check out SweetNight; you’ll be glad you did.
