We suggest purchasing an optional cover for the topper to help prevent tearing of the foam and increase longevity. Reviews ... My daughter was adamant about getting a loft bed which limited our mattress height options. I was sure she would have to forfeit softness & comfort to accomodate a thinner mattress. I called customer service and they helped me choose the perfect combination to fit her needs according to her weight and sleep style preference. We went with 4 inches of HD36-HQ and 2 inches of 4lb ViscoPlush topper.

4 Inch Toppers | Mattress Firm
Whether your current mattress is starting to feel a bit too firm or you’re simply looking to enhance your sleep experience, a 4 in mattress topper provides a generous buffer that can help relieve pressure points and promote better alignment throughout the night. This thickness is especially appreciated by side sleepers or those who experience discomfort in their hips and shoulders, as the plush surface helps cushion sensitive joints. For anyone sharing a bed, a 4 inch foam mattress topper can also help minimize motion transfer, making it an excellent choice for light sleepers or couples with different sleep schedules.

Mattress Topper Thickness – 2 Inch, 3 Inch, or 4 Inch?
October 8, 2025 - The average thickness range of a mattress topper typically falls between 1 and 4 inches. However, some specialty toppers may be thicker or thinner, depending on the materials and intended use. A 3-inch thickness is the best when you're starting out with a new mattress topper purchase.

r/Mattress on Reddit: 3 inch vs 4 inch mattress topper?
April 7, 2023 -

I have decided to purchase a memory foam mattress topper to help support me when I sleep (I'm about 230-240 lbs and a side or back sleeper with some back problems).

Although my mattress was comfortable when I first bought it I just need something to help distribute my weight evenly so I don't wake up with sore hips.

I've read conflicting things about topper depth. Some people say that 3 inches isn't going to be supportive for long enough for someone heavier. And other people have said that 4 inches "folds like a taco" when you sleep on it and you can't move.

Anyone have any experience or insight to add. I don't mind having to flip/rotate it every so often and replace it in a couple of years. I'd prefer that to being unable to sleep comfortably right off the bat. But I want to make sure it will support my back and hips.

Check the density of the topper – the density decides the thickness and the materials made for this product. A springier mattress topper will give you more support and of course, will be more comfortable. A four-inch thick topper offers more significant support for the sleepers who want to reduce pain from the back, hips, or shoulders.

r/Mattress on Reddit: 4" latex mattress topper as matress
April 17, 2024 -

Hi,

My husband and are in the market for a new matress and he noticed that we could save about 300$ buying a 4" organic latex mattress topper instead of a 6" Sleepez with firm and soft side (Roma Mattress.) I like the savings, but am worried that 4" latex on the ground will be too hard. I'm 135 lb side sleeper. Husband is mostly back sleeper and says he feels perfectly comfortable on a 3" peice of memory foam that he sleeps on in his van. If we got the 4" topper, could another cotton pillow top topper make it more comfortable for me if I found it too hard?

Its going to feel very firm and you will feel the firmness of the floor through the latex. The pressure on your shoulder and hip would be unbearable for most side sleepers. Adding more soft comfort layer isnt the solution either, the support(Your floor) is just too firm. What will likely happen you will either feel the hard floor underneath, until you have added enough soft material that instead of your shoulders and hips hurting your back will hurt from bad alignment. There is a really inexpensive solution though if youre trying to save money. Just get 5" of the HD36 High quality foam for $135 in queen and you have yourself a mattress. They also sell Lux HQ foam which is extremely firm at 50ILD, he might like that better, but I would think the HD36 HQ has a better chance of working for both of you than the Lux. Edit: Another comment suggests a want to stay organic, having a memory foam topper suggests otherwise but I figure I can expand on my advice anyways. Probably the cheapest option keeping it somewhat natural would be some Caliber edge coils for $230. Then you just set the topper on that and you have a latex hybrid. All of this is DIY territory though so it should also be noted that most of the time when you go down this route you will not get it right the first time. You usually have to make adjustments, eventually you want to get a mattress encasement to hold it all together, it can be quite a thing. This guide here is a good starting point if you go down that route. Also if you end up going with the Roma, just keep in mind that soft side is more like a med-firm side, and it isnt a natural mattress at all either. It has supersoft foam quilted into the panel.

I'm dealing with the same exact issue...I really appreciate the first response here but if I'm not mistaken the organic and non toxic characteristics of these mattresses are important to the person who has made the original post here and foams will produce toxic vapor ( off gass ) if you don't want to breath chemicals you're in one heck of a ride finding mattresses that don't off gass...
