For those of you that need a little more cushion added to your mattress, our 4lb memory foam mattress toppers are the solution. We offer a mattress topper that is perfect for those seeking that final piece that will allow them the best night of sleep they've ever had. Our 4lb memory foam mattress toppers come in multiple sizes, starting at Twin and going up to California King, so no matter what size mattress you have, we have a topper to fit it. It also comes in varying thickness, so you can choose from 2 inches to 4 inches thick.
4lb memory foam mattress toppers offer great solutions to everyday issues. Memory foam molds to your body while in use, so it matches your unique shape to give you the best support for your body. It also matches temperature, which is great during summer and winter, when the temperatures hit their extremes. If you're used to waking up with stiffness, this will solve those issues. The memory foam reduces stress on pressure points, and allows for better circulation, so you will wake up feeling refreshed and ready to take on the day.
We have various covers available to add additional comfort to your memory foam topper. Please click here for information regarding covers.

I’m new to memory foam. I went with the 4# 2” topper, it seemed like a nice middle ground. It was softer than I expected; I wish I had ordered the 5# for a firmer feel. But the 2” was sufficient to add the memory foam effect to my old mattress. It has definitely improved my sleep, much less tossing and turning during the night; I typically change positions only once and then it’s morning. I also wake up feeling less sore and achey. I was hoping for the topper to reduce motion transfer from my partners moving - it does not. However, he is sleeping better too so that’s a plus. I like it enough that I’d like to purchase a memory foam mattress which I hope would be better for reducing motion transfer. Overall, I’m sleeping better than I was so it’s a win.

If you buy from Amazon, you will almost never get a straight answer regarding the density of the topper you are purchasing, so the quality is all over the map. With this company, you get what you pay for. I ordered the cover. The quality of the cover is uneven. I ordered 2. One came with snags, the other was perfect. I used both as even the one with snags was functional. The cover has a slight smell, so I washed. The topper had no smell at all. These have transformed my beds into spa like retreats. I bought 3” 4lb king toppers.

2" of this 4lb density was softer than expected but still not quite soft enough as a topper for our 4" HQ foam base. (I'm a tall, skinny who likes firm support but needs some soft for the bones.) I was planning to replace our 2" latex topper with this since that wasn't soft enough. Then I decided to try both toppers - memory foam on top of the latex -and it's just right for my bones to sink in gently- the latex helps it spring back nicely when I roll over. It's so nice to find affordable options to make a custom mattress that's right for our unique preferences!

I read a review that said 2" was the sweet spot and decided to try it for my 118lb 91 year old mother. I purchased the gray and white striped cover for the topper. My mother loves it. She said it is comfortable and she can get in and out of bed with no problem.

We bought the 2” 4lbs density and it’s wonderful. Definitely high quality, compared to the ones you buy on Amazon. I was worried it would be too hot, but it actually isn’t. We are used to memory foam beds and use a “cooling” protector. I am wondering if I should have purchased the 3” for my shoulders, but then I worry it might be too much sink for my hips. When you’re buying online, it’s hard to really know what will work. Very glad I took a leap and bought it.
Almost perfect.

Top notch company. Great communication and service, great products. After months of waking up stiff found the solution.

My wife and I have only had this topper for 4 days, but we are already sleeping better than we ever have on our mattress. I could not be happier with the quality and feel of the foam.
We went with the 2” thick viscoplush. The pressure relief is great, and it is the perfect “middle ground” of firm and plush, where it is just right.
I have had multiple toppers in my life and this one takes the cake without a doubt. I’m so happy I did my research and found foam by mail. Will definitely be ordering more products in the future.
P.S. Make sure to buy a cover for the topper. It will help keep the memory foam from tearing.

I am very pleased with the foam topper, but I am especially pleased with the incredible service I received. I will order from this company for any future foam needs.

The quality and price of the Viscoplush memory foam topper is the best deal on the internet. Added a 2 inch viscoplush topper to my DIY mattress build and noticed an immediate difference compared to other inexpensive memory foam toppers that I have tried. Highly satisfied with the feel, pressure point relief and price for a high density memory foam topper. I have been recommending this topper to others on the mattress forums.

My parents purchased this topper to put on top of their adjustable air mattress and love it! Adds a great layer of additional comfort.

I bought the 3" for a guest bed. So comfortable, I turned around and bought the 4" topper, which was placed on top of a 5" foam mattress I'd already bought from these folks. Let the 4" one air out a little longer. This is the only company I trust with my sacrum, L-5, L-4, and L-3. I've bought the stuff made in China. That's not memory foam. THIS is memory foam, and you can tell it's made in the USA. I live in Tucson, and this mattress is not hot at night like the other memory foams stuffed with gel and who knows what. 'Nuff said.

Ordered this, along with the 4" memory foam mattress, for my daughter and she LOVES IT!! I ordered the mattress and topper in a King Size a few years back and it is by far the most comfortable mattress I've ever slept on!!

I bought the 4 lb memory foam in 3 inch size. Product is wonderful. Relief of joint pain and better rest and sleep. I would highly recommend.

Pretty much - if you need it - foambymail.com can supply it. They have many options are very reasonable prices. Be comfortable ordering here.
Tasha | August 16th, 2022
This is the 2nd order I've placed with them and love it as much as the first! Bought the 2" for my camper mattress and love it. I do however like for my home bed a 3" 5# foam to be able to "sink" in a little more for molding around my curvy hips. I will definitely order from this company ANYTIME I need foam!
Sheryl | August 13th, 2022
Terrific service. Garrett went above and beyond for customer satisfaction and service. Prompt communication. Great product and price. Totally renewed my dual chamber bed.
Vicki Noble | July 26th, 2022
This was my second order from foam by mail! The first, a new camper mattress. We slept like a baby on it! Perfect fit! The second order, a replacement foam insert for our Select Number mattress. Perfectly measured, perfect fit! Better than original foam, and the mattress is more comfortable than it was new!! Quick, well packaged delivery! Great company to work with! Will always give them any business I can!!

I am very pleased with the fast service I got when placing my order. Was here within 2 weeks and I had also ordered the cover for my foam topper and to my surprise they had already put the cover on the topper. What a relief as I am 83 years old and was wondering how I was going to put the cover on. Slept on my "new" bed last night and it was wonderful. Thank you Foam Mattress.

We have been using a 4 inch foam mattress topper for years. The quality and density of the major brand we used to buy has been decreasing despite their claim it was still 4lb density. This one is as good as the first one we ever bought! I certainly notice the difference in my back.

Couldn't be happier with the foam! The 4lb 2in.memory foam is the sweet spot! Remember that!

I got the 4LB ViscoPLUSH Memory Foam Topper - Blue Twin 39" x 75" size, 2". I've been sleeping on it for about a week now and it is amazing. So far, it's great for my severe fibromyalgia. Like sleeping on a marshmallow - in the best sense. No complaints here!
Susie | May 4th, 2022
This is an incredible topper! Soft, cushy, but not too soft. Made a waaaay too hard mattress tolerable and will now be the comfort layer on my diy mattress. No off-gassing! CS is fantastic! Super fast responses and very helpful! Sent foam samples to help make my choice. Very pleased! I wish you guys offered topper covers. Otherwise, you have everything I need for my bed & the beanbag I am making with the now un-needed toppers I discarded in favor of this one! High quality product!

I have bought a few different toppers from different places and this one is the second best I have gotten. Years ago, I bought one that I really loved but Haven't found another one like it since. This topper is a little too soft when I am lying on my back. It seems to work pretty well when I am lying on my side though. I weigh about 140 and my son weighs around 120 and both of us would prefer a little firmer topper. I am thinking about getting the 5 lb topper. One wonderful thing about this topper that I have never experienced before is that there was so bad smell! I was so happy about that because I have asthma and any chemical smell bothers me. And I mean ANY.

I had a customer who needed a custom cushion and wanted memory foam as part of it, I used Lux foam as the basis on 3/8 inch plywood, covered with the memory foam and marine vinyl. I used trimmings of the memory foam on the wood. He is very happy with the comfort and his caretaker likes the easy cleanup.
Jeremy Brown | January 22nd, 2020
I had a foam by mail 4" 5LB memory foam topper and a 3" 3LB memory foam topper before I purchased a 4" 4LB topper, and while it was a great balance of support and comfort, it was too thick and my mattress sheet ended up pulling off every night. I replaced the 5LB 4" topper/3" 3LB memory foam topper combo with a 4" 4LB topper, and while it is slightly stiffer than my old combination, I enjoy that my sheets do not pop off the corners of the mattress in the middle of the night.

2 years ago we moved and purchased a memory foam mattress at our new place. Having had a memory foam mattress at our old house for 7 years which we loved, we ordered another one which we thought was similar but have not been happy with it. They memory foam layer was just didn't seem to have the same blend of softness and support as our old one and we were convinced it was inferior. Most manufacturers really don't list the specifications like country of origin or density. It was surprisingly difficult to find one but did find a 4LB USA made topper at foam by mail. When it arrived we put it right on top of the old mattress but found we would sink in too far. The next day we flipped the mattress over, put the topper on it and it is perfect. The inferior memory foam layer is now facing down and our 4LB topper rests on the what was the mattress bottom being a standard foam base or whatever it may be. After a week of sleeping on this we are very happy. I find myself sleeping for longer periods and turning less. I highly recommend this topper for anyone searching for a high quality memory foam.

Perfect! I love this pad. I replaced a 4 inch 5lb pad which was a little too firm for me.
This one has the perfect balance between softness and support. Would buy again, for sure.
