So, what is the Cocoon™ by Sealy made of?

basic features of sealy cocoon

Take a look at the basic features of Cocoon™ by Sealy, depending on the cover option:

Cover – Classic version: The Classic version of the Cocoon™ mattress features a premium fabric cover made of spun poly fibers (blend of polyester and cotton), which make for a breathable, stretchy, durable and soft to touch cover.

Cover – Chill version: The Chill version of the Cocoon™ mattress features a phase change material, similar to the ActiveX mattress by Nest Bedding.

This technology basically regulates temperature and absorbs and stores body heat so that it changes accordingly: it cools off when the temperature is high, and it warms up when it is low.

This temperature regulator cover enables a cool sleep. Similar to the classic version, the Cocoon™ Chill is durable, has enhanced breathability and is soft and stretchy.

The rest of the Cocoon™ by Sealy consists of:

Top layer: 2’’ of memory foam for great body contour and great pressure relief to ensure the perfect sleep.

Second Layer: 2″ of poly foam acting as the comfort layer for a more “in-the-bed” feel. The firm layer will provide more of a sturdier, “on-the-bed feel. This layer works as the proper transition from comfort to firmness and it is really the reason why the Cocoon™ is so supportive and comfortable.

Third Layer: 6″ Support foam which is the foundation of the mattress and is highly durable and resilient. This layer will ensure your spine is well supported all night long.

The Cocoon™ mattress by Sealy comes in two firmness options, soft and firm.

firmness scale

The soft option is increasingly favorable among the two options, ranking at a 6 out of 10 in the firmness scale, where 10 is the firmest.

On the other hand, the firm option ranks at an 8 out of 10 in the firmness scale, with 10 being the firmest. Both options now include the personalized comfort layer which can eliminate any pressure points and can cater for all types of sleepers. The firm option is still quite hard though.

Comfort and Support

The manufacturers at Sealy managed to produce the sort of pressure relief, deep compression support and the perfect amount of support for any type of sleeper.

This beautifully designed mattress is, without doubt, a gem as you will not experience any discomfort whatsoever.

Sinkage and motion transfer

Whilst the sinkage levels differ depending on the firmness chosen, overall the verdict is that it is unlikely you will feel trapped deep into the mattress with the Cocoon™ by Sealy. The soft option leaves a pleasant hugging feel to the sleeper, whereas the firm although too hard, could be appropriate if you prefer no give at all.

On the other hand, you will be happy to hear there is virtually no motion transfer with this mattress. This is probably one of its highlights, as the memory foam and supportive blend of foams allow for zero sense of movement. This means there is no chance you will sense your partner turning and tossing at night.

Doesn’t sleep hot

The Phase change technology which comes with the Chill cover of the Cocoon, together with the blend of different foams, make for an exceptionally cool sleeping surface.

Do not worry though, if you stick to the Classic version, you will still get a satisfying result in terms of cooling effect.

Therefore, there is no reason to worry about sleeping hot with the Cocoon™ Mattress.


Perhaps the most important disadvantage of this mattress is its strong odor upon unpacking. There have been several complaints about off-gassing of the Cocoon™ Mattress.

Indeed, our personal experience suggested it may take up to a week for the smell to dissipate completely. The best advice on this respect is to air the mattress for a day or two and then keep the windows and doors open if possible until the smell wears off.


The Cocoon™ Mattress is manufactured in the USA and scores quite high based on owner satisfaction with much great feedback.

Shipping and Return policy

The Cocoon™ Mattress by Sealy is handcrafted in the USA so it takes about 2-3 days to arrive at your doorstep via UPS.

The standard shipping is free of charge within the contiguous USA. The company also offers a 100-night risk-free trial, which means that if you are not satisfied with your mattress within 100 days from purchase, you can claim a full refund.

The company will pick up the mattress and donate it to a charity, which is good to know.

Value for money:

Our belief is that the Cocoon™ Mattress by Sealy is available at great price point given its premium features and will not disappoint. You can check the different pricing depending on size and cover option.

Twin $399 $549
Twin XL $449 $599
