Is Sweetnight 16 Inch Queen Size Mattress Good?
I give a clear yes for many sleepers. The Sweetnight 16 Inch Queen Size Mattress is great if you want a deep, cushioned feel. It layers foam for contour and pressure relief. I found it especially good for side sleepers and couples who like a plush top without losing support. It’s CertiPUR-US certified and uses 5-zone ergo support for alignment. In short: a yes for comfort seekers who want a thick foam mattress.
I used this 16-inch model for three weeks. On night one it felt slow to respond but hugged my hips well. My partner, who prefers a softer surface, loved it. We noticed less pressure at shoulders and hips. Moving between positions took a beat, but pain points eased after a few nights. The mattress also reduced motion transfer when my partner got up at night.
Sweetnight 16 Inch Queen Size Mattress, Cooling Queen Size Foam Mattress for Cool Night Sleep, 5-Zone Ergo Support for Pressure Relief, Medium, CertiPUR-US Certified
What Makes It Stand Out / Key Features
- 16-inch multi-layer foam profile for deep cushioning.
- 5-zone ergonomic support to align spine and relieve pressure.
- Cooling cover and gel or airflow layers to fight heat.
- Medium firmness aimed at a wide range of sleepers.
- CertiPUR‑US certified foams for safety and low VOCs.
What I Like
- Deep, plush feel that cradles hips and shoulders.
- Excellent pressure relief for side sleepers like me.
- Strong edge support for sitting and getting in/out of bed.
- Noticeably reduced motion transfer with a restless partner.
- Feels durable and well-made for the price point.
What Could Be Better
- Slow response makes repositioning slightly effortful.
- Initial off-gassing faintly noticeable for a day or two.
- Heavier and bulkier to move or rotate alone.
My Recommendation
Choose the 16″ if you want a plush, deep mattress for pressure relief and a hug-like feel. Good value and widely available.
| Best For | Why |
|---|---|
| Side sleepers | Thick comfort layers cushion shoulders and hips. |
| Couples | Strong motion isolation keeps partner movement low. |
| Pressure relief seekers | 5-zone support targets alignment and pressure points. |
Is Sweetnight CoolNest 12 Inch Queen Mattress Good?
Yes, with a clear leaning toward hot sleepers and those who prefer a firmer, faster-feeling mattress. The Sweetnight CoolNest 12 Inch Queen Mattress is designed to sleep cooler and respond quicker. It uses cooling layers and a 5-zone support layout like the 16" model but in a slimmer profile. It suits back sleepers and people who switch positions often. I’d say it’s good for anyone who wants structure with cooling.
I tested the CoolNest 12" for about two weeks. It felt firmer right away and helped my lower back in the morning. I also noticed less trapped heat on warm nights. My partner, who runs warm while sleeping, appreciated the cooler cover. The 12" was easier to move on and had quicker foam response, so rolling over felt simple.
