Trimming a Memory foam mattress

[10brink]

Has anyone attempted to trim a memory foam mattress. If you did, how'd that work out? The pros want $1000 for a custom fit queen mattress. Seems a little steep to me.

I used an electric carving knife to cut a 3" thick latex foam mattress. It worked reasonably well. I've heard of other people doing the same on memory foam.

Electric carving knife or hot knife.
Google "electric hot knife foam carving"

In the film biz we use both for all kinds of foam work.

I have made custom size memory foam mattresses before. Go to ebay and get one from vendor "maw and paw bargains " don't be scared off by the low price. The cover zips off and you can sew it on any sewing machine. I paid over $1000 for a king size Temperpedic and the $250 mattress from ebay is just as comfortable.

50 year old electric carving knife did the job just fine for me.

Thanks to all for your generous time!

A regular, old bread knife worked for me.

Electric knife works. Or find a local marine upholsterer that deals in form. Ours here in Pensacola uses a band saw and the mattresses come out perfect.

We love our "budget" memory foam from Amazon more than our $3,000 tempurpedic mattress.

Plus 1... Electric carving knives work nicely

Electric knife hAs worked for me too.

I didn't have an electric carving knife. I just made templates for top and bottom, marked it out with magic marker and used a really sharp carving knife. The electric knife does a better job of completing the cut in a single pass. The carving knife needed to be used with multiple passes but it worked out just fine.

As others have mentioned: BREADKNIFE.

Bought memory foam from Walmart 6.5 years ago as original AS mattress really, really hurt my back. Walmart memory foam still working fine and I'm full-time.

I was surprised, but was able to do a 3" with heavy scissors. Good luck.

OK... Here's my solution to sorry Airstream mattresses:

I found a Foam Mfr'r......www.foambymail.com contact email is: info@foambymail.com or by phone at: 586-627-3626.

They will make any size or thickness...but it's important you measure accurately the height and width and thickness you want.

I ordered their most-firm...and it is a bit too firm, so we placed a egg-carton soft 2" foam cover on it and now it's a fantastic mattress. If I had to do it over, I'd order the next softer level.

I ordered a 60"W X 84"H X 8"Thick (full queen) for my 22' Sport (2008 model, in which we lowered the dinette permanently for a bed....we'll never use a dinette... we eat on the lounge-sofa using folding TV-tables. Beware: later 22' Sports have a slightly narrower mattress, so measure yours carefully.)

Their product arrived in a few days exactly as ordered. I used an electric carving knife to cut the two rounded corners ... after I marked it with a Pilot-point marker, using the original Airstream mattress as a template. It worked out PERFECTLY (except as to it being more firm than I would have wished.)

The total cost, including shipping was $438.60.

We do not like "memory foam" because we don't like the "puddle" it makes one lie within. We ordered the "latex" mattress and it accommodates you without making you feel like you're in a puddle, and it does not make you feel hot.

When they made this for us, they actually glued/vulcanized a 2" foam sheet onto a 6" foam base to make the 8" I actually ordered. If I had it to do over, I'd ask if they'd glue/vulcanize a 2" soft foam onto the 6" firm foam.... as I think that would be the best solution of all (for our personal tastes in firmness.)

Mind you, my wife and I like a firm mattress ...and in our home we have a Posturpedic FIRM... but the Foam by Mail degree of firmness was simply too firm for us, as mentioned first in this message. (It's a shame there's no show-room to try 'em out first...but you readers can benefit by our experience hopefully.) Again...we are now FULLY SATISFIED with our egg-carton foam on top of their most-firm model. And their quality is excellent, as is their shipping and service.
I should also mention they claim their latex has a life expectancy of 16 years!

Most important...IT DOES NOT SMELL!

Ditto on scissors. Easy Peasey.

We ordered two twin xl memory foam/foam 4" toppers from Amazon with zippered cover to cut down to fit our Classic twins. I used my very sharp Bubba Salmon knife and a box cutter. Cut 3" off the width to 36" and used a cardboard template to draw the corner radius and cut that. First used the box cutter with a new blade to follow the line by hand to cut through the memory foam and followed that line with the long Bubba blade to slice through the remaining thickness. Worked great and easy, just take your time. Zipped it back into the case, loose but doesn't get in the way of the fitted mattress cover.

Hi Boxite....Thanks for the detailed explanation! I've read a few comments about the "puddle" in the memory foam. Honestly, we've never tried one. I'm going research this more before we buy. We replaced our couches and dinette in the front of our '67 Safari with a full futon. Too small for both of us so we're going as close to full queen as we can get. Thanks again and also I appreciate all the posts!

Boxite, did you get the LUX Firm foam mattress? Did you make a custom cover or have them do the custom wrap?

Here's what my order states. I did not ask for any cover whatsoever. We placed a 2" egg-carton corrugated foam on top of it (Walmarts) and found it very comfortable on our 6 week trip recently. (We actually agreed, after 6 weeks on it, that we might like it better than the expensive mattress on our bed at home.) You might wish to review my earlier comments in this thread.
We covered the entire thing with a "California King" mattress cover my wife re-sewed to fit. It was essentially nothing more than a heavy-duty percale fitted sheet.


Mattress, Lux Foam - HQ (M)
Dimensions: 8" x 60" x 84" 1 $436.80 $436.80

Shipping: Free Shipping: $0.00
Sales Tax: $0.00
Total: $436.80

The thing arrived via FedEx in a couple of days, all shrink-wrapped in a vacuum-bag/plastic-wrap. We carefully cut the wrapping off and the mattrass unfolded itself upon a spare bed in our guest-room. We allowed it to expand for 24 hours, then trimmed it, and rolled it up (difficult) and transported it into the Airstream. It was heavy...likely around 70 lbs. Extremely good quality, accurately measured when it arrived. I actually trimmed another inch off one end so DW had a bit more room between mattress and walls and could more easily make up the bed in the airstream.

Made the first cut with a box cutter. Folded the foam back and cut through the rest with kitchen shears.
