FAQs

Cocoon by Sealy

Is the cocoon mattress good for heavy person?

The Cocoon Chill mattress performs well for back sleepers of all weights, particularly those between 130 and 230 pounds. However, those under 130 pounds may find it lacking in cradling, while those over 230 pounds may experience some sinkage around their hips.

Is the cocoon by Sealy worth it?

The Cocoon Chill mattress offers good value for its price. It's a solid, all-foam mattress that provides a dense memory foam feel, making it a suitable choice for those who enjoy this type of feel.

Is cocoon a mattress in a box?

Transform your room with a Cocoon by Sealy 12"™ Medium Hybrid Mattress in a Box. Enjoy premium gel memory foam and supportive fabric coils that allow for increased airflow, limit motion transfer, and provide a core support layer powered by Active Support Technology®.

Simba 1500

Can I clean my mattress?

Yes, you can clean your mattress using light fabric cleaning products or a soft, damp cloth. However, we do not recommend removing the cover.

Will I be able to get the mattress back in the box?

Once the mattress is out of the box, it cannot be put back inside. We also do not recommend attempting to fold or roll it as this may damage the spring layer inside.

Will my mattress have a smell when i first open it?

There might be a slightly unusual smell for the first few nights due to the fresh-out-of-the-box foam. However, this smell will fade away after a few days and will not return.
