This frame is absolutely phenomenal, especially for bigger folks. I'm 6'7" and 325. My wife is 6' and 300. This frame is as quiet as a mouse, supportive, and barely even moves during Wild Monkey Aerobics. It's unbelievably sturdy and doesn't sag, squeak, or even wake up the cat sleeping under it during the most frenetic The Kids Are Asleep Green Light Seal Team Six-Style enthusiasm. **Q: What is the difference between the Elite and the Standard models?** A: It’s much more heavy duty. I had the standard and broke the weld points of the wire in a few areas during some “activities” where my knees were on it. The elite is much stronger and The supports are a lot thicker. Plus, it’s quieter, barely making any noise whereas the standard would squeak. **Q: is the elite worth the extra money over the regular?** A: I haven't tried the regular; but, I feel more secure with the more solidly built elite and I also took the revies of the regular into account in making my decision. **Q: I have several storage bins. What is the actual clearance under the bed. Is it a full 14"? (My tubs are 13 3/4 " tall. Will they fit?)** A: the size is 14" but there is a bar which means you will have to lift the bed a little to get a bin 13 3/4" tall out from under the bed even with a mattress is easily lifted. ## Frequently Bought Together - ZINUS SmartBase Super Heavy Duty Mattress Foundation with 4400lbs Weight Capacity, 14 Inch Metal Platform Bed Frame, No Box Spring Needed, Sturdy Steel Frame, Underbed Storage, Queen - SafeRest Waterproof Queen Size Mattress Protector - Fitted with Stretchable Pockets - Machine Washable Cotton Mattress Cover for Bed - ZINUS 12 Inch Green Tea Memory Foam Mattress [New Version], Fiberglass free, Medium Firm Feel, Zoned Pressure Relief, Certified Safe Foams & Fabric, Bed-In-A-Box, Queen --- ## 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.hr/products/383873691-zinus-smartbase-super-heavy-duty-mattress-foundation-with-4400lbs-weight](https://www.desertcart.hr/products/383873691-zinus-smartbase-super-heavy-duty-mattress-foundation-with-4400lbs-weight) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-19*
