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®.

Casper Nova Hybrid

Is Casper Nova too soft?

The Casper Nova may be perceived as overly soft by heavier sleepers. This is because the more weight applied to a bed, the softer it feels, and the Casper Nova is already a soft bed. However, if you prefer a softer bed, the Casper Nova should provide comfort.

Is Casper Nova good for back pain?

The Casper Nova is excellent at promoting healthy spinal alignment for lightweight sleepers in all positions and average-weight sleepers who sleep on their sides or backs. The zoned support foam and pocketed coils provide pressure relief and firmness in the necessary areas, helping to alleviate back pain for these sleepers.

Does Casper Nova Hybrid come in a box?

Yes, the Casper Nova Hybrid is a bed-in-a-box model, meaning it will be delivered compressed and rolled in a box.
