Couch foam replacement
Upholstery foam suppliers and not all foam is the same so undo the zips and take out the liner and take it with you to the shop. This will make sure you buy the right density foam and have it cut to size and you may choose to do a sandwich with a less dense square on either side and a denser square in the middle. A good upholsterer will advise you. Worth replacing the cushions and design you already have. Then you can rotate them to keep them olumped. More on reddit.com

Replacing couch cushion foam with trimmed down memory foam mattress?

I mutilated a couch when I was pregnant, it was a sofa w/ chaise and I decided I didn't want the chaise anymore. Well, it was all attached and my pregnant brain told me it would be ok to take a butcher knife to the chaise lounge and just cut it off, replace the filling and turn the cushion around (I didn't want to sew it back together). Anything you do to a couch will probably be better than cutting off the chaise.

Replacing the filling went ok, the memory foam is a good choice. The problem that I encountered, other than cutting off the chaise, was that the new foam didn't match the old foam, so the seats were different heights, even though the foam was technically the same thickness. So, imo, doing all the cushions is a great idea- you won't have a weird seating headache later.

For the foam I would look around for foam that is one solid block of the same foam. Cutting through two different thickness of foam is difficult and can come unmatched with the bottom layer. If you're planning on using wire, you get pretty much use whatever foam you'd like though, a hot wire cuts foam like butter.

On the hot wire cutters- they have a lot of different small ones out there, but they are small. Most probably won't be large enough to go through a mattress; however, if you can't find one you can use the same trick chefs use to cut cheese: Heat your knife first, then cut. It'll take a while to heat, cut and repeat, but it's worth it to not have to struggle with cutting through cold foam.

In the end you've got a fairly easy process, just do not cut off your chaise.

I need to replace cushions in a couch and have a thick queen mattress worth of a memory foam topper. I was considering doing to layers of the topper cut to size as inserts for the couch cushions. Is this a no-no or is it ok?
It would work if you used it as a 2 part layer with something denser beneath. Otherwise the topper will sink way too much for a comfortable seat. More on reddit.com

Has anyone used a mattress to replace couch cushions?
Tbh this sounds like a great idea. For me the huge plus would be getting rid if the extra "crevices" between cushions. The only downfall I can think of is if the cushion cover needs washing rhe whole couch is "naked." More on reddit.com

People also ask

Can I replace the foam in my couch cushions?
Replacing foam in couch cushions is easier than it sounds! The choice to change foam usually depends on personal preference. Some people prefer a firmer cushion, while others like something softer. The most common reason to change foam is to refresh your furniture by replacing the old, sagging inserts.

Which is the best type of foam for sofa/couch cushions?
The ideal foam depends on your comfort preferences and how you use your sofa. High-density foam works well for many customers who prioritize firm support and long-lasting resilience. For those who love a plush, cloud-like experience, soft fiberfill layers provide exceptional comfort. Each option has its own benefits, and we're happy to help you find the perfect match for your lifestyle and seating needs.

Is memory foam good for sofas?
Although memory foam offers great advantages as a mattress topper, it is not recommended for use as a cushion due to the lack of support it provides on its own. Memory foam can sometimes be used as a layer on top of a thicker, firmer base to provide some extra comfort.

r/upholstery on Reddit: Couch foam replacement
December 28, 2024 -

Context: I have zero knowledge of upholstery or how any of this works, so please lmk if none of this makes sense or would look horrible.

I have a 3 seat gravel grey Burrow Nomad couch and one of the the seat cushions are in a sad sunken condition with some staining from I don’t know what. Looking to do one of the following (the frame itself is in fine shape):

  1. Replace just the cushion that’s sunken and buy cushion covers.

  2. Replace 3 seat cushions with one long bench style cushion, and potentially the back cushions with two long pillow style cushions. Will have to get covers here as well.

In either of those two cases, I will need to buy foam replacement - where can I get this? And is there any recommended place to get sofa cushion covers as well?

If any of this is bound to break the bank I might as well replace the couch but I’d prefer not to. Disposing furniture is my nightmare.

I'm also a complete noob when it comes to upholstery. However, I'm in the process of building my own sectional sofa. Which means I was also needing to find appropriate foam for the cushions. I did a lot of research and ended up buying some from GoToFoam from amazon. They have a lot of options for length, width (24" or 30"), and thickness (1" to 6"). They also have options for either firm (44 ILD) or semi-firm (36 ILD). I was wanting something a little more comfort oriented, and bought three of their 30" x 72" cushions, 6" in thickness and choosing the semi firm (36 ILD) version. Can't speak to its long-term durability, but initial feel is good. The semi-firm is definitely still firm to me (6', 180 lbs). I'll be adding some thick dacron to help both fill it out, and to create some additional "plushness". As for covers, for now I'm just going to use some stretch covers. Which is fine for my application of casual seating. For a more formal room, this likely wouldn't work that well. In my research, I'd found a local supplier that sold both "high" and "regular" quality form. The difference between the two is the high has greater density (2.8 lb/ft3), while the regular is (1.8 lb/ft3). In short, the former is supposed to last around 15 years. While the latter is rated for 7-10 years. Obviously this will be dependent on how often the seating is used, the weight of the users, care, etc. The stuff I bought from GoToFoam is the "regular" quality (1.8 lb/ft3) density. Which I was OK with given the significant cost savings. From the local supplier, the "high" quality would have been $275 for each 30"x72"x6" cushion. Their "regular quality would have been $225 per cushion for the same. While the cushions I got from GoToFoam off Amazon were only $60 per cushion. What I figured is that I'd have to replace the GoToFoam cushions 5 times in the 15 year period before I spent the same as if I'd bought the "high" quality foam from the local supplier. With that in mind, I just couldn't justify paying the premium at the local place. FWIW, the stuff GoToFoam sells is supposedly made in the USA, and shipped super fast. Making it from their factory in CA to my house in the midwest in 2-3 days. Even though amazon was projecting it would take a week or two to get to me. Before ordering I called them to inquiring about shipping times, and they said they typically ship Amazon orders the same day, and if not they'll ship the next day. Good luck!

r/DIY on Reddit: Replacing couch cushion foam with trimmed down memory foam mattress?
January 29, 2014 -

My couch is only about 2 years old but the foam is worn out. I like the couch design, shape, fabric, and color but the foam just isn't holding up. It's a sectional with a chaise. The cushions are 8 inches thick.

The middle cushion where I normally sit only has about half of the initial support now. The chaise can't be laid on for long as the part where my butt goes sinks lower than the rest and ends up making my back sore.

So I was looking at getting replacement foam. It's certainly not cheap. Online retailers, such as this one, want $75-$140 just for the middle cushion which is 36x30x8. The chaise is much larger at 68x43x8. All in all I'm looking at ~$400.

So instead I thought about buying a 8 inch memory foam mattress and cutting that down to size to fit my cushions. A king mattress should be enough to redo the entire couch.

Amazon has several 8 inch mattresses that are memory foam on top of regular high density foam. Mattresses just as this or this or this.

Anyone have any experience with something like this or any thoughts why this would or wouldn't be a good idea?

I've done this. Overstock sells a twin foam mattress for about $200; it works great. The one I bought (I'll dig up the link if you'd like) was actually three layers of foam glued together, which gave you more thickness options. Use an old electric carving knife to cut the memory foam.
