Two Mattresses. One Perfect Night's Sleep.
The Serta iSeries NXG 3500 Medium Split King gives you and your partner the ultimate in personalized comfort — two Twin XL mattresses that pair seamlessly together to form a Split King, each delivering Serta's signature coil-free, all-foam construction with advanced pressure relief and all-night temperature regulation. Made in Texas, this is premium sleep engineered for Houston.
⚠️ Please Note: This listing is for the two Twin XL mattresses only. Adjustable bases are NOT included and are sold separately.
Why Choose the NXG 3500 Medium Split King:
- Set of 2 Twin XL Mattresses: Together they form a Split King — each partner gets their own sleep surface with zero motion transfer between sides.
- All-Foam Construction: No coils — just premium performance foams layered for contouring comfort and body-hugging support from edge to edge.
- Cool-to-the-Touch Cover: A breathable, cooling cover helps regulate temperature and keep you sleeping comfortably through Houston's warm nights.
- Advanced Pressure Relief: Multiple foam layers adapt to your shape, easing pressure points on shoulders, hips, and back for restorative sleep.
- Medium Feel: Perfectly balanced between plush and firm — universal comfort for couples and all sleeping positions.
- Reinforced Edge Support: Stable edges for sitting, sleeping, and getting in and out of bed with confidence.
- Made in Texas: Crafted domestically with Serta's trusted reputation for long-lasting support without sagging.
- Adjustable Bases NOT Included: These mattresses are compatible with adjustable bases, but bases are sold separately. Contact Gallery Furniture to add an adjustable base to your order.
