Enhance the performance of your mattress with this 4" Zinus Night Therapy wood and metal box spring. The premium-grade metal frame serves as a sturdy support for the entire bed, while the tough wooden slats help absorb weight, deliver consistent support and extend the longevity of your mattress. Wake up recharged and ready for the day ahead with the even support delivered by this heavy-duty mattress foundation. This Zinus Night Therapy wood and metal box spring can accommodate a memory foam, latex, polymer and innerspring mattress, although it works best with an all-foam mattress. This box spring foundation doesn’t come with a traditional innerspring system so you can expect whisper-quiet performance for many years. In place of spring coils, wooden slats help absorb impact and keep the bed bouncy and durable after many years. A high-quality white fabric casing offers a polished look that complements most bed linens, room interiors and motifs. Add four inches to your bed’s profile with this Zinus Night Therapy wood and metal box spring. You can also set this foundation on top of a bed frame with legs for additional height. A higher bed profile gives you the luxury to dangle your feet at the edge of the mattress, while a low-profile bed may be ideal if you have kids who love to crawl into bed or if you simply want to complement a minimalist design. Optimize your space by placing this box spring and your mattress on top of a bed frame with legs and under-bed clearance for extra storage space where you can place extra pairs of shoes, bulky luggage and spare linens.

For long-term satisfaction, pair this bed foundation with a high-quality mattress that suits your body type and the way you sleep.
