The BedBeam supports tremendous weight! Each leg supports up to 1240 lbs! (More than half a ton. The King Size Bed Beam comes with THREE suspension beams, with legs. This Bed Beam Support System is designed for king size beds that measure approximately 76 inches wide. (Eastern King) Today's heavyweight sleep products are too heavy for wooden slat systems. When weight is applied to old fashioned wooden bed slats, the siderails bend outward, leading to complete failure. Conversely, the Bedbeam legs are composed of a high-tech reinforced composite material with interlocking ribs that lock securely into place. Another plus of the BedBeam is that its very design allows for you to move your bed without damaging or affecting the characteristics of the support system. Moving any bd across the floor will put a large amount of force on center support legs. Because traditional metal bed frames are not designed to accommodate movement, many will collapse when the bed is moved. This Bedbeams' 3 leg posts adjust from 5" to 18"! Adjustable width: adjusts from 75-3/4" to 79-3/4" wide. Adjustable height: Each Bed Beam Leg is adjustable from 5" to 18" in height. The Bedbeam works with wood beds that meet the following criteria: Must have wood side rails. The side rails must have a cleat or lip. The wood cleat must be between 5" - 18" off the floor. Made in the USA by the country's leading bed frame and support system manufacturer! ## Features - Adjustable from 5" to 18" High - Prevents Box Spring Damage - Attaches Securely to Wooden Bed Frames - King Size Suspension System - Three Beam System ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B079NQPQ8V | | Best Sellers Rank | #3,912,204 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #2,129 in Bed Replacement Parts | | Brand Name | Bed Beam | | Color | Black | | Compatible With Mattress Size | King | | Customer Reviews | 5.0 5.0 out of 5 stars (2) | | Finish Types | Painted | | Furniture Finish | Black | | Ground To Item Distance | 5 inches | | Included Components | [Adjustable Legs, Suspension System] | | Item Dimensions | 76 x 76 x 5 inches | | Item Dimensions L x W x H | 76"L x 76"W x 5"H | | Manufacturer | Knickerbocker | | Manufacturer Warranty Description | The bedbeam comes with a lifetime manufacturer's warranty. | | Material Type | Cast Iron | | Maximum Weight Recommendation | 1240 pounds | | Number of Items | 1 | | Number of Packs | 1 | | Other Special Features of the Product | Adjustable | | Size | King | | Style Name | Modern | | UPC | 702534525935 | | Unit Count | 1 Count | ## Product Details - **Material:** Cast Iron - **Product Dimensions:** 76"L x 76"W x 5"H - **Size:** King - **Special Feature:** Adjustable - **Style:** Modern ## Images ![*King Size* Knickerbocker Deluxe (K783)- Premium Bed Suspension System - w/ 3 Adjustable-Height Legs - Image 1](https://m.media-amazon.com/images/I/51db0FyBXYL.jpg) --- ## 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.ro/products/104928585-king-size-knickerbocker-deluxe-k783-premium-bed-suspension-system-w](https://www.desertcart.ro/products/104928585-king-size-knickerbocker-deluxe-k783-premium-bed-suspension-system-w) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-10-16*
