How do I fix a chair that has bottomed out and sinks in the middle?

Hello, we address the situation with on our leather sofa. Here is what we had to do.

Our sofa was very expensive and custom ordered —it was a big relief to add the seat support modification. This sofa has a recline mechanism on the right side and the left side is plain fixed seating with an ottoman. It was the plain fixed seat side that sagged. I confess Im normal weight and BMI!

In our case —this third saggy seat is removable from the other two seats, it slides up and out in a slot -locking the mechanism together. As you might guess it made making this repair easier being a smaller working area. I say this beause your interior skeleton structure may be different than mine.

But certainly worth a look—- as this enhancement does improve both the function, seat comfort and look of the furniture .

After removing the stapled dust cover we assessed the situation and initiated our repair with supplies we had on hand. We added some padding which happened to be a memory foam mattress remnant and it was placed and supported by a 1x 4 piece that we had it on hand.

The existing interior wooden framework was measured and a length of 1x4 larger than the frame was cut and placed on top of the frame for support and this was screwed in place. It was attached to the interior existing wooden structure sideways with screws using the Dewalt screwdriver.

The black dustcover was restapled on the bottom.

You may or may not need additional padding. You may just need the wood support for your existing saggy cushion.

Regular foam sometimes wrapped with batting—also makes excellent replacement filler too.

I hope these details may help you address your situation

Hi ! If the bottom cushion lifts off , put a wood board down , under the cushion .
