Homyfort Couch Cushion Support for Sagging Seat - Sofa Saver Protector Insert Board Sagging Cushions,Sofa Replacement Parts Fit Most Couch with Non-Slip Durable Surface & Thick MDF Board

We have one of those no box spring needed king size mattresses. That is true. BUT the foot of the mattress kept getting sat on and pushed between the cross-rods. They are only 4 inches apart. Who knew?! So, we bought this hoping that a couch stabilizer would work since it is the just the foot of the bed and way / WAY more reasonably priced. What did we have to lose?! I am so Happy we ordered this. It works. I mean it works. Mattress does not move at all. Still stays put. We also sit properly at the foot of the bed with comfort and ease. Feels like it's all brand new again. Thank you so much for having this product and the perfect size. HIGHLY Recommend. Very fast as well. I am sorry I was not able to get pictures. When all was said and done, you could not even see it anyways. The mattress and frame hid it. Oh, and before I forget. When I changed the sheets, I didn't even have to try to get it lined up right so it would not fall in between the bars. Love It!!
