Review: Worked with an old futon - The springs on the old futon (bought back in 1998) broke and the seat wouldn't set up. I thought I would try to replace the hinges before throwing out the futon. They fit perfectly in the current holes and it works like a charm. The only issue is that the new futon mattress is so stiff it is hard to position upright from the bed to a seat. I'm sure once the mattress wears in a bit, it will become easier. ## Features - 【Specification】: Top Length: 13", bottom length: 14.1", the height when use: 6.1" - 【Great Material】: Made by high quality heavy duty steel These hinges have 2 positions functions: Couch and Bed Suitable for Sofa bed or you can DIY for your own furniture - 【New Design】: The difference between these hinges and the Standard Hinges is that they operate from the front When you lift the seat the hinges click and then release.

I thought I would try to replace the hinges before throwing out the futon. They fit perfectly in the current holes and it works like a charm. The only issue is that the new futon mattress is so stiff it is hard to position upright from the bed to a seat. I'm sure once the mattress wears in a bit, it will become easier. ### ⭐⭐⭐⭐⭐ Direct replacement for popular cheap metal futon *by S***S on November 2, 2023* The hinges on my cheap tube steel futon that's kept at a lake cabin basically exploded with the arms bending and rivets pulling out. It's a DHP which is available in multiple styles but all with the same hinge. I was shopping new futons which stunk because I had a nice mattress on this one and was really glad to find that the hinges could be replaced easily instead. ## Frequently Bought Together - NATGAI Sofa Couches Bed DIY Adjustable Spring Mechanism Futon Hinge Hardware Triple Click Hinge Hardware for Sleeper Sofa Bed Furniture - Sleep Philosophy Waterproof Sofa Bed Mattress Protector, Holden Sofa Bed Full Mattress Pad, 3M Scotchgard, Microfiber Mattress Topper Fitted Elastic Pocket Fits Up to 8 Inch, Full 54x72, White - Milliard 4.5-Inch Memory Foam Sofa Bed Mattress Replacement for Queen Size Sleeper Sofa & Couch Beds – Premium Comfort (Sofa Not Included). --- ## 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.us/products/168299498-natgai-sofa-couches-bed-diy-adjustable-spring-mechanism-6-1](https://www.desertcart.us/products/168299498-natgai-sofa-couches-bed-diy-adjustable-spring-mechanism-6-1) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-12*
