There is no denying the importance of a great night of sleep. It can help you wake refreshed and ready to take on another day. With our Lux-HQ foam mattress, find an affordable sleep solution to help make the most of every night of rest.
When looking for a bedding solution that is affordable without ever compromising on the important elements of comfort and support, foam just makes sense. Made of durable material that carefully balances cushioning softness and reliable firmness in one convenient product, foam mattresses help provide relief and alleviate pressure while maintaining proper body support and firmness. The Lux-HQ foam mattress provides a supportive, firm feel like its Lux-Regular counterpart, but with a greater material density that equates to a longer product life and increased durability. All this, while still providing the pressure relief and comfort benefits of a foam mattress. When looking for a long-lasting option that is firm without being uncomfortably hard, this is a great choice at an even better price. Choose from several options for thickness and size all the way up to California king to get the right option for your needs. If you have any questions about this reliable and comfortable solution, please contact us for assistance on the matter. We are always happy to help in any way!

I've used this product on bench seats in a camper and its the only 4 inch thick high density foam I've found to not bottom out to the board underneath when sitting on it (that's for a 180 lb person). So we tried a 6" mattress - I like firm but this is just too much. Maybe with the addition of some sort of topper it might be ok but with the distributed weight of a person laying down on 6" foam, its just about like laying on the floor. Furthermore, don't expect returns to be easy. I explored it in detail and would have to pay the original shipping ($30) plus return shipping (more due to size) and unless you have some way to mechanically compress the mattress, it will never fit back in the box that it came in... thus returns are not particularly cost effective. In my opinion, the HD36-HQ foam is a much better option for a firm mattress - your experience and personal weight may drive a different conclusion. Overall though, the mattresses are great products, service is good. We've placed more than 5 orders and will go back again.

Such a great product shipped fantastically! I would definitely order from them again. Saw this business on Reddit, took a chance and love it. Bought a 5 inch and a 3 inch foam and a 3 inch latex topper on it and it is the best bed in the house.. I highly recommend it go for it

The mattress is really comfortable and firm and the cover is totally worth getting. Free shipping and great customer service.

This mattress is very nice it’s very hard and I like hard when ever you sleep in mattress then your body feels good and I sleep very well.

I recomend Foam Factory for the products as well as the people I've been in contact with. I've had years of dissapointment with the comfort of traditional mattresses. I've had my Foam Factory mattress about a month now and I am well pleased with my comfort so far. First time choosing the foam was a large task for me. I first chose a combination then asked custmer service rep. Haley to assess how it works together. That helped me make a good decision. One that I am pleased with. So go ahead Make Your Own Night.

We were searching for a good high density foam for our van & this was perfect! We had originally purchased some not so cheap foam from the craft store, but it went flat pretty quickly. Upon further research, hd foam is the way to go. I'm very happy with my purchase

I am writing to thank you for your expedient shipping AND ABOVE ABOVE ABOVE EXCELLENCE in product and service.
After my "move" I was stupidly talked into getting a "coil mattress" which was a very BIG BIG BIG mistake on my part. :(
I "tried" that stupid coil expensive mattress and MAYBE got - in the beginning total - 1 to 2 weeks (over a 36 month time span) of a "good nights" sleep...if you can call it that. :(
The foam products (2- 2ftx4ft HQ Lux foam and cover) that I've purchased from you in the past was my life raft, and my "expensive mattress" was - in my opinion - just for show...
Last night - after waiting for inflating lol - I was PURE HEAVEN! No "coils" poking. Even body weight distribution (I'm only 120 lbs). No body part pressure. You have no idea how grateful I am for crossing paths with your company.:)
Additionally, I will tell EVERYONE about Foambymail.com. :)
Thank you! Thank You! THANK YOU!

I finally found the firmest of the firmest mattresses! I've walked into mattress stores that offer "firm," but they are always too soft for me. The Lux HQ Foam Mattress is truly firm. It's been about a month, and my body is finally adjusting to firmness. I've slept on a memory foam mattress for over 7 years, and that mattress was starting to lose its quality and make me sink in, which makes it hard for me to get out of bed in the morning. With the Lux HQ Foam Mattress, I can roll around quickly and get out of bed without fighting it or sinking in. It'll take a couple more months until my body fully adjusts to how firm it is, but it'll be worth it as it helps readjust my body throughout.

Excellent service, excellent quality. That's all that needs to be said - can't recommend these guys enough. This is the 2nd time I've bought from them.
JB | December 2nd, 2024
This is the second project we've done with Foam Factory's products, and once again, we are completely satisfied. The Lux foam is firm and sturdy, and delivery was prompt. Would not hesitate to purchase from you again!
Marilyn M | November 6th, 2024
Firm 4" foam is a perfect fit on an aging mattress. Gave it new life and me too. Much better sleeping. This took no time to expand when removed from the vacuum-sealed bag. Good price for quality foam.
Joe L | October 24th, 2024
Ordered the queen size HQ-Lux, 4 inches thick. It arrived in a timely manor and was everything as advertised.
Teri Gilman | October 24th, 2024
The base foam for our mattress has worked out perfectly. Also have to commend your customer service, very helpful over the phone and email discussions were timely. Wouldn't hesitate to buy from you again.
Kayla P | September 4th, 2024
Ordered the 6" queen size and it's incredibly firm, I call it a "soft rock". After a few nights I don't mind the firmness and my back pain has went away! With a soft topper it would be wonderful.
R H | September 4th, 2024
Was glad to find this excellent company and product. The Lux-HQ Foam 5-inch Queen standard mattress is very supportive and firm. Put this over a current unsupportive mattress and am sleeping much better. Thank you for your excellent company and excellent Lux-HQ Foam Mattress, Foam Factory!
Customer1 | September 4th, 2024
Overall good product, I have been using for 2 weeks now. If you are going to use everyday, I would suggest a stronger version, I can see it developing a permanent depression where your heaviest body parts lie. I am planning on rotating it around every now and then. No smell of foam at all. Arrived timely, no hassles.
Angela Chighizola | July 23rd, 2024
Im replacing my 12yr old queen tempur pedic memory foam with a twinxl. I bought 6in LuxHQ for my base. Its very firm and great quality. I also bought the 2in pink 5lb memory foam. It is great for sleeping on your back but im mostly a side sleeper and I need more give so I ordered the 4 in 4lb blue memory foam.
Maryann Kirk | July 3rd, 2024
Had this 3" of the Lux HQ for support on Platform bedframe. 3" inches worked out perfectly for a twin size. Great foam for sturdy support level.
Traf | June 19th, 2024
I ordered 6” of this as a base for my mattress. It’s very firm and solid. I put 2” of hd36-hq on top and that’s a bit softer. The combo of these two together make a great base for adding a topper of your choice. I am using wool batting of 3.5inches. You could also use latex, softer foam, or memory foam.
Hakim | June 19th, 2024
Been buying from Foambymail since 2017. Good product and fair price. Just wish they would wrap individual pieces separately for shipping.
Tim | June 6th, 2024
I needed a very firm mattress for camping and travel. The HQ Lux foam mattress met my need and I'm very pleased with it.
Logan | April 25th, 2024
Insanely supportive. Got it in 2 inch and cut it to size to use as a camping mat. It is both more supportive and comfortable than anything I ever got in stores across many different purchases, even blowing $250+ dollar brand name camping pads out of the water for a fraction of the price. However, I put a trifold mattress on mine (car camping.) If you used just a sleeping bag I would go up to 3 inches. Would work extremely well as a base for a DIY mattress as well.

I got this specific density block of foam to replace my rv mattress. The only thing I need in life is a mattress that supports my hips and shoulders as a side sleeper, and after growing weary of people recommending memory (aka garbage) foam, I finally realized I was rarely in pain when sleeping on hard couches. I could sleep on either this or the 1.8lb, but I chose this for longevity. Zero off gassing wait, it was all I could do to not immediately take a nap. What a game changer. And the price! The next competitor wanted like $500 for something similar, and there was no way I was paying that for a naked block of foam. I will be purchasing again for my house mattress. And it will be from the foam factory! Btw: 4in is plenty for this density. Heck, 2 would have probably been enough. I would get bare minimum of 4in in the 1.8lb though, just me.
Amy | April 24th, 2024
I ordered several foam pieces of varying sizes and firmness. I am impressed with everything I've ordered from Foam Factory. Also their customer service is excellent.
Jason Burgher | April 24th, 2024
I was looking for some tougher foam for my bed. This stuff was a great value for the product that received thank you.
Linda | March 19th, 2024
330 pounds- hard to find a truly firm base. Changed out my 7 inch coils for 6 inch HQ-LUX... kept my 3 inch talay top and named my new bed format - The Brick with a bit sore hips but such better sleep and back pain gone.
Softened up with a 1.5 inch poly foam topper from local market since cheaper than paying shipping... perfection!
Second time using this product. Last year replaced my 'new' sofa cushions which was graded for 1000 pounds, but the original cushions had no support for my 330 pound body- hurting my back. HQ-LUX perfect replacement and I loved napping on sofa- figured would work for the bed base...Thanks for making a great product!
Bob | March 19th, 2024
So glad to know this site exists!!! I really struggled to find exactly what I needed, and I'm so glad to have finally found the right option for supporting my extremely picky back.
Jon | March 19th, 2024
Finally decided to buy this bed and it works well as a base layer for my diy mattress. However the price dropped $50 the next week and they don’t do price adjustments, so keep that in mind.
Deanna | February 14th, 2024
I love a super firm bed. I slept for many years on the floor with just a mat, so most beds don't offer the support I want. This mattress totally fits the bill, it is exactly what I wanted!! Just enough give to be comfy with all the support.
clk | July 8th, 2023
We are using this on top of an older memory foam mattress. The extra sport has been wonderful. We are now sleeping great again.
Stephen Mott | June 16th, 2023
The shipping was timely and the Lux HQ is quality stuff.
Siegfried Wolf | June 13th, 2023
Added 3” Lux HQ to 1” Dunlop Latex Topper with Gray and White Striped Cover. Just completed 3 night camping trip. Very satisfied with our sleep quality.
B | June 7th, 2023
Heavy box was torn to shreds, left at bottom step of porch and difficult to get into house and unpack. But the mattress is excellent. The firmness is perfect for a bad back.
Lynn and John | May 19th, 2023
As usual, I got exactly what I ordered. Good quality twin mattress. I have used always use Foam-by-mail for all my beds for years.
lance | May 1st, 2023
So for me and my disability a good mattress is crucial for me to be able to walk. and I'm very happy to report this 6"(with the Dunlop Latex Foam Topper 3") is the only one I've had that hasn't caused issues. I first had a twin, then when I moved out I got a queen, both the exact same materials and I couldn't be happier. the twin mattress is still in great shape as well after about 8 years of wear and I only got a new one because of the size. The price is also great, comparable queen mattress were pushing me into the $1000 range and this one was almost half that. the only thing I would note is that it is very heavy, so take care when moving or lifting it. but yeah, I recommend this mattress (and topper) to any of my friends who are looking for a new mattress and I'm sure I will be ordering again in the future.
Jake Buller | April 6th, 2023
I bought it, it doesn't smell, and works feels nice. POG item
Kristen N. | March 15th, 2023
We are very happy with the foam mattresses from here! We have bought a total of three and would never go back to a traditional mattress. We have put one on both of our boats and have one at home. Suffering from back and shoulder injuries, the foam allows a wonderful cushion for pressure points. This allows us to sleep well. These are so much better than a foam mattress topper, which eventually becomes saggy. We highly recommend!
Michael | February 14th, 2023
This is good foam. So good I bought a second one for what I needed. Only downside is major static when using with latex, so be careful.
Shaina | January 30th, 2023
I was looking for a firm foam that I could sleep on with nothing else on top. Other reviews made it sound like some people who preferred firm beds did this with this lux foam. I have learned that this ILD is way too firm to sleep on by itself. It is extremely firm and bounces back in an amazing way, like it will never break down. It will be a GREAT base foam but I wish the site had explained this better. The foam I bought is too large for a base foam and I found the descriptions on this site to not be accurate. I highly recommend doing outside research before purchasing.
N. | November 23rd, 2022
Excellent product for comfort, quick delivery, and customer service. *Please note that this foam off-gasses for more than a month and is quite strong smelling. It hurt my eyes and throat and I would not recommend sleeping on it right away. That being said, this is my second order of this product. I just left it out in my sunroom to air out until I could tolerate breathing the fumes. Overall, I am satisfied with the product and the company. Knowing what I am in for, odor-wise, I would probably order again.
Mark | October 22nd, 2022
I bought a 5” king Lux-HQ foam as the base for a DIY mattress. It works great for its intended purpose and the ordering process and shipping were extremely smooth. I will definitely order from here again when the need arises. Thanks!
S.V. | October 2nd, 2022
When we received the mattress it was very firm and very supportive of my bad back. After a month, the position where I sleep has become softer, still firm but not very firm as it originally was.
Steve Adams | September 8th, 2022
I was making boat cushion replacements and it was hard finding the foam overall size and the firmness I needed so I did not have to cut and glue pieces together to make the cushions the right sizes. Foam Factory had the size and the firmness for my requirement, and it was top quality. The order was shipped pronto, and it arrived much earlier than I expected. They personally verified the order details with me and were on top of the entire shipping process. Thanks.
Eva | August 24th, 2022
I needed to replace my old mattress . It took 7 days to air out and last night was the first night we slept on it so glad I found this company. Will be purchasing another one soon.
Willem Frederik | August 3rd, 2022
We needed to replace the mattress on our boat and decided to pick the same product that we had purchased before from the foam factory for our chairs. It's a very firm foam but for us we love it!
We had to cut it to fit our bed and that was easy too! We used an electric knife! We also purchased the mattress cover which made the whole process go smoothly and look great. We should have done this years ago!!
We will be making more purchases from the foam factory as we upgrade the foam in our other chairs and boat cushions!
Terri | July 14th, 2022
I put off buying this foam for some months because at the price I was afraid it would be poor quality. I am very happy to say the quality is great and it arrived in perfect shape with no smell at all. I just ordered a second piece today.
Dennis Portello | July 7th, 2022
I recently purchased a used cal king sized Purple brand mattress. Unfortunately it had some issues with the cover so I ordered a new cover giving me an additional 3". I decided to add some firm lux foam. My only complain is that some foam had to be glued at the factory to meet the cal king dimentions. This gluing has not made a difference with my mattress, the lux foam has definitely made the Purple mattress more comfortable.
Clay | June 21st, 2022
Use this foam to replace the topper on my Sleep Number.... It is now a NEW bed and VERY Firm. of course now the air pressure does not mean much, but WOW, it is a very comfortable firm mattress.
Bunch | June 15th, 2022
Packaged great and when opened there was no off-gassing and it's firm but forgiving and the 6" is perfect for cushion for our dinette/bed in our travel trailer.
LH | June 13th, 2022
Good foam, good deal. Wish this place carried the same foam as FoamOrder.
