About the Twin Size Cooling Gel Memory Foam Mattress, Medium Firm, Fiberglass Free Y87821

This twin mattress is made of cooling gel memory foam with a medium-firm feel. The foam contours to the body to relieve pressure and support the sleeper. It is fiberglass free.

The design promotes ventilation and helps move heat and moisture away. The soft, breathable cover allows continuous air circulation to help keep the sleeping temperature comfortable.

The foam is CertiPUR-US certified, and the cover is OEKO-TEX STANDARD 100 certified. The mattress arrives compressed in a box. After unboxing, it expands and can be used right away, though full expansion to the specified dimensions takes 24 to 72 hours.

Questions and answers

Is this mattress good for side sleepers?
The medium-firm feel may be too firm for some side sleepers, who often prefer a softer surface to relieve pressure on hips and shoulders. Back and stomach sleepers typically find it supportive.
Does the cooling gel actually keep you cool?
The gel and breathable cover are designed to dissipate heat, but cooling gel mattresses generally feel cooler only initially. Sleepers who overheat easily may still prefer a latex or hybrid mattress with more airflow.
How long does it take to expand?
The mattress arrives compressed and typically expands within 24 to 72 hours. It is ready for use once it reaches its full shape, though minor odors may linger briefly.
Is it compatible with an adjustable bed base?
Yes, memory foam mattresses like this one generally work with adjustable bases. The foam conforms to the base's movements.
What is the firmness level?
It is medium-firm, which provides a balance of support and pressure relief. Most back and stomach sleepers find it comfortable, while some side sleepers may find it too firm.
Does it contain fiberglass?
The product name indicates it is fiberglass-free. The foam is CertiPUR-US certified and the cover is OEKO-TEX certified, so it should not contain fiberglass.
