In their words

What customers say about this board

4.7 out of 5 7854 reviews of our 21.5″ to 30″ deep sizes

Very helpful product

Very happy with this purchase. I have a full size couch with recliner chairs on either side. Instead of buying a couch sized support board, I purchased two chair sized boards. It works perfectly for the recliner chairs and makes them much more supportive. The center of couch doesn't have a support board and that works for me as well don't tend to use the center. The support board is very effective.

Works well

Good overall. Definitely improved the seat support of my oversized club chair. I believe this is a good solution to delay having to replace the chair in a couple of years or so. Happy with the results.

Gives sagging couch cushions a boost

High quality product that has made my old sagging loveseat much more comfortable. Also, this is one of the few couch supports that has a size for a smaller loveseat (42" wide).

Nothing to screw, cut or glue. The board rests on the seat base under your cushions and stays out of sight.

  1. Take the cushions off

    Take the cushions off

    Lift off the cushions to reveal the flat seat base underneath. This is where your BEN'SHOME support will rest.

  2. Lay the board on the seat base

    Lay the board on the seat base

    Lay the support flat across the seat base and slide it all the way back for a secure, even fit.

  3. Put the cushions back

    Put the cushions back

    Put the cushions back and sit down. The board stays hidden underneath and gives the seat a firmer base.

Find your numbers on the list

If you already know your numbers, skip the questions and pick straight from here.

Measure before you order. Take the cushions off and measure the bare seat base, inside the arms and from the front edge straight back. Cushions overhang the frame, so measuring the cushions gives the wrong size. Not sure? Send us your numbers and we'll confirm.

Worth saying plainly

When this is not the answer

The board solves one problem: a seat base that has gone soft underneath the cushions. That is what is wrong with most sagging sofas. Here are the cases where it is not.

A frame that has cracked or given way

If the sofa creaks under you, leans, or one corner has dropped, the problem is the structure rather than the seat base. A board laid across the seat will not straighten a frame.

Springs that have snapped rather than stretched

Webbing and springs that have slowly gone slack are exactly what this is for. Metal that has actually broken needs a repair, and the board would sit on top of the fault rather than take its place.

Cushions that are worn right through

The board gives your cushions a firm base to rest on. It does not put thickness back into foam that has collapsed. If the cushions themselves are thin and flat, you are looking at new cushions as well as a board.

A sofa bed

It helps with the sag, but it cannot fully cancel out the folding mechanism underneath. Go in expecting an improvement rather than a fix.

You like sinking into your sofa

This makes the seat firmer. That is the whole point of it, and it is the wrong buy for anyone who wants soft. We would rather say so here than have you send it back.

Before you order

Things people ask

What does this product do?

It sits under your seat cushions and gives them a firm, even base to rest on. When the webbing or springs underneath have stretched out, the cushions have nothing solid to land on, and you sink. The board puts that support back.

How do I know which size to order?

Use the size finder. Pick your furniture, then tap the width and seat depth of the bare seat base, measured with the cushions off. It shows you the one size made for those numbers. If you'd like a person to confirm it, send us your numbers before you order.

Will it make the seat too firm?

It makes the seat firmer than it is now, which is the whole point. Most people are looking for exactly that. If you like sinking into your sofa, this is not for you, and we would rather say so here than have you send it back.

How firm is it? From soft, you sink in, to firm and level. With the board the seat is on the firm, level half. Your own cushion stays on top. Thin cushions: you'll feel the board.

Can it fix a very old or badly damaged sofa?

It helps when the problem is soft support underneath the cushions, which is the usual cause. It will not rescue a cracked frame or snapped springs. If you are not sure which one you have, send us a photo of the bare seat base and we will tell you straight.

Does it slide around?

It rests flat on the seat base under the cushions, and the cushions and your weight hold it in place. It is not an anti-slip product. If your cushions already slide forward, tell us before you order.

What is covered by the warranty?

The board itself, for as long as you own it. If it cracks, splits, or the panels come apart, we replace it free. Send us a photo and we will send a new one. You keep the old one, there is nothing to ship back. A warranty card comes in the box. This covers faults in the product, not damage from something else happening to it.

How long does delivery take?

Free shipping across the 48 contiguous states, usually about five business days. Tracking is emailed when it ships. We do not currently ship to Alaska, Hawaii or military addresses.

What if the size I ordered is not the right match?

You have thirty days. Return shipping is at your cost, and the refund goes out as soon as it arrives back in good condition. Easier still: send us your measurements first and we will confirm the size before you buy.
