    I notice a huge difference in my jack knife sofa on how it sits now. No more dip in the middle. Was easy to put in. Will put it to the test in a couple weeks and let people know how it feels with it being in the middle.

    Easy to install, great support

    I watched the video before buying and knew I would need help to install. I bought two as most of the people I fish with are bigger guys. It was well worth the price to use two and not just one.

    Jake knife sofa support

    The product seems good. Seems like a ridged design. Took all the sag out of the sofa. Easy to install. The only down side to this was the package was severely damaged from Speedee. Just like everything else I’ve ordered from Smokey Hills and speedee. Speedee could screw up a wet dream.

    Does it's job

    Easy to install. The support definitely improves the stability of the outside edge of the bed. The only down fall is that it does add another uncomfortable bar in the middle of you back. This is to be expected since that's where it has to be to support the bed when folded out.

    Awesome Products Great Service

    Bought a pair of these at the last minute to support the sofa before my wife took the Castle to We Fest. Called to make sure they had these in stock on a Thursday and he told me they do and if I got my order entered in a few minutes he would ship them right out. The came standard delivery on Monday and super easy to install. Great product and great service from the team at Smokey Hills!

    Great addition

    what a simple idea. but the idea is over executed, most certainly. This is a very solid bar that provides significant support for the front couch.
