This is the BEST box spring I have ever owned. If you’re on the fence about buying this product, or you’re trying to decide between options, here’s a number of reasons to go with this one.1. Noise Level: NONE. Completely silent. This was my #1 reason for wanting a new box spring in the first place, and it does not disappoint. Our previous box spring (the traditional wood/spring kind) had become squeaky over the years, and kept waking up our 5 month old baby. This new box spring hasn’t made one tiny noise since day one - our baby has been sleeping through the night. Relief is an understatement.2. Sturdiness: I have never felt so supported by my bed. It feels even better than when our previous box spring was brand new, so I know it’s not just because it’s new. I have chronic shoulder pain, and while a new box spring obviously isn’t a cure, I have been waking up significantly less sore for the first time in years. My husband doesn’t have the same pain issues, but he agrees that our bed feels much more sturdy and comfortable, because our bodies are better supported.3. Assembly: So easy. I am not in my greatest shape (I did just have a baby), but I was able to put it together without my husband’s help. The box comes with some screws and an Alan key, and that’s honestly all that’s needed. The directions are pretty easy to follow. I will say that the “Up” stickers were placed on the parts in a way that was a little confusing at times, but if you pay close attention to the pictures in the instructions, you’ll be fine. It took me less than an hour.I cannot recommend this box spring enough. Do yourselves a favor and purchase this. You can thank me later. :) ### ⭐⭐⭐ calidad precio *by on Reviewed in Mexico 18 July 2025* esta muy chica de ancho mi colchon es individual y esta mas grande que esto pero de ahi en fuera facil de armar y no es muy caro ### ⭐⭐⭐⭐⭐ Love it!!!!! *by on Reviewed in Canada 20 April 2026* Went together so easy. Strong and sturdy. I dont have mine on top of a metal bedframe, using this to get an open frame look to match the loft bed I have over queen bed.. But for people saying its weak or bending on frame, your metal bedframe must have a center bar to support the center of this just like any quality frame should have supporting a wooden box spring. I didnt use the cover so cant make opinion on that. The mattress i have on it is an older 12 inch high Zinus hybrid that is heavy as heck. No creaking, rattles, and stays put. The mattress does sink down a bit in between bars when laying on it as a bigger person, but since in spare room not to worried about it. It would be nice if had few more cross bars but not a dealbreaker. For everyday use Id put a board under the area where main body weight would be. If bed frame in my room broke (which is a Zinus folding smartbase) Id buy one like this. ## Frequently Bought Together - Zinus 9 Inch WonderBoxTM Smart Box Spring, Quick Assembly Mattress Foundation, Durable Metal Frame, Full - Utopia Bedding Water and Bed Bug Proof Mattress Encasement (Full) - ZINUS Shawn 35.5 cm Metal SmartBase Bed Frame, Platform Bed Frame Without Box Spring, Sturdy Steel Frame, Under Bed Storage, Twin --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/687896804-zinus-9-inch-wonderbox-tm-smart-box-spring-quick-assembly](https://www.desertcart.no/products/687896804-zinus-9-inch-wonderbox-tm-smart-box-spring-quick-assembly) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-30*
