The Oasis Twin Mattress with Regular Foundation by Palm is designed for sleepers who prefer a plush sleep surface with supportive comfort beneath. Made in the USA, this mattress features a soft stretch knit cover and TheraCool® Quilt Gel to help create a cooler, more breathable sleeping environment. TheraSponse® HD Extra Firm Transition Foam helps relieve pressure while providing the support needed for consistent comfort and stability throughout the night. Foam-encased edge support improves perimeter stability and maximizes the usable sleep surface, making the mattress feel supportive from edge to edge. Breathable construction encourages airflow, while Stability Base Foam enhances durability and long-term performance.
