The Serta Kozma is a 10-inch plush-soft gel memory foam mattress that comes with a 10-year limited warranty. This Serta model is discontinued.
Great for pressure relief and motion reduction. Decent mattress, if you enjoy the enveloping/cradling feeling of memory foam. Suitable for hot sleepers due to its gel in the top layer.
Skip if you dislike foam feel (you like bounce and laying on top of the mattress). Too soft for stomach or back sleepers (bad for spinal alignment).
Loom and Leaf is the #1 alternative you can buy. Their 5 lb. memory foam density is extremely high quality and built to last. Euro-pillow top and soft organic cotton cover contours to your sensitive pressure points and provides tremendous overall support. Their customer service is excellent (probably the best of all brands) and their policies are generous.
- Ideal for side sleeping
- Decent height (indicates a sturdy mattress)
- No motion transfer
- No info about weight (lack of spec details = red flag)
- Average edge support
There are no online reviews, which is typically a red flag! Consider alternatives like the Saatva Classic. This model is our #1 pick, with over 51,028 5-star reviews.
The serta kozma comes in a plush soft firmness (give-or-take a 3-4 on a 1-10 firmness scale).
A soft model like this is built for side sleepers that have sensitive pressure points (neck, shoulder, arms, low back, hips, etc).
Stay away if you sleep on your back and stomach at all. You won't have enough firm support for your spine and cervical alignment, which is critical for a back or stomach position.
The top style does a good job maintaining a flat and relatively even sleep surface even with substantial enveloping.
The Serta Kozma is excellent for side sleepers.
Make sure to choose their most soft option. If you're not sure which model it is, contact them.
Anticipate bearable support for fragile pressure points (specifically your shoulders, hips, neck, low back). The top foam layer relieves tension and pressure throughout the body fine.
NOTE: Be sure that your shoulders, hips, and torso all receive equal support if you sleep on your side. This reduces the possibility of chronic pain from concentrated pressure.
The Serta Kozma is poor for stomach and back sleepers.
Ensure to select their luxury firm (6.5/10), firm (7/10) or very firm (8/10) offering. If you're not sure which model it is, chat or call with them.
Count on acceptable support for spinal and cervical alignment (specifically your lumbar area). Relatively firm foams on the top layer keep your back straight poorly.
NOTE: Focus on finding a mattress that won't sink too far into your hips when sleeping on your back & stomach. It'll throw your spine out of alignment.
The Serta Kozma has several layers worth exploring:
• Bottom Layer: foam for sturdy support.
• Transition Layer: foam for padded pressure relief.
• Top Layer: gel foam for additional comfort & overall support along the top layer.
• Top Design: tight-top which does a fine job creating a larger sleep surface (good for couples).
• Cover: no cover information available which is fairly standard.
• Bed in a Box: no information available.
• Weight: unknown weight (queen size).
The serta kozma height is 10".
• Moderately Good edge support because of its foam design.
• Loom and Leaf is a dazzling alternative if you want remarkably good edge support.
Note: If a mattress uses low-quality materials, it might feel supportive at first, but break down FAST.
Inadequate edge support means less sleep surface (which is not desirable, especially if you sleep with a partner).
Bank on terrific motion transfer as a result of the foam design.
You and your partner won't sense a single bit of motion transfer, and explicitly won't wake you (whether you or your partner are heavy sleepers or not).
NOTE: Motion transfer is how much movement transfers from one side of the bed to another. Sleep on a mattress that offers effective motion isolation if your partner tosses and turns.
A better night's sleep leads to a happier life.
