Plush, not mushy
Soft, Plush Mattress Toppers for a Bed That Is Too Firm
A soft mattress topper is the fix for a bed that is too firm: a new mattress that has not broken in, a hotel-hard guest bed, or a hybrid a partner chose. LOUNJ makes plush toppers two ways in our Phoenix, AZ factory, 3 and 4 inch gel memory foam for a slow, cradling sink, and 24 ILD Talalay latex for soft with bounce.

All Mattress ToppersSoft should still be supportive
The mistake people make with a soft topper is buying the cheapest, fluffiest thing they can find: a fiber-filled pad or a low-density egg crate. Those feel plush for a week and then flatten, and while they last they let the hips drop, which is how a soft bed causes back pain. A good soft topper cushions the shoulder and hip so pressure disappears, but it is dense enough to keep the spine level under your weight.
That is why our soft options are 3 and 4 inches of gel memory foam that we pour ourselves, and Talalay latex rated at 24 ILD. Both give you a plush surface on top of real support. If the mattress underneath sags, though, a soft topper will make it worse; look at the firm topper page first.
Gel memory foam: the cradling kind of soft
Memory foam is soft in a particular way. It gives slowly as it warms, molds to the exact shape of your side profile, and holds it. For a side sleeper on a firm mattress, that means the shoulder sinks in and the hip is supported at the same time, which is the feeling most people are after when they type “soft mattress topper”.
Our Gel Mattress Topper in 3 inch is the plush choice for sleepers between roughly 130 and 230 pounds. The 4 inch is the softest thing we make, the right pick for heavier side sleepers, for a mattress that is extremely firm, or for anyone who wants to disappear into the bed. Both are gel-infused and open-cell so the plushness does not come with heat, and the foam is CertiPUR-US certified with no fiberglass.
24 ILD Talalay latex: soft with bounce
Not everyone wants to sink. If you change position a lot, sleep hot, or dislike the stuck feeling memory foam can give, Talalay latex at 24 ILD is soft in a livelier way. Talalay has a very uniform open-cell structure that yields easily at the surface while staying buoyant underneath, so pressure at the shoulder and hip goes away but you float on top of the topper rather than settling into it.
ILD, or indentation load deflection, measures how many pounds it takes to compress the foam by 25 percent. Our 24 ILD is the softer of our two Talalay options; 28 ILD is medium. At 3 inches, 24 ILD latex turns a firm mattress into a plush one and stays cool all night. Latex toppers are made to order through our custom quote form, with a reply in 1-2 business days.
Picking the right soft topper
- Side sleeper, 130-230 pounds, on a firm mattress: 3 inch Gel Mattress Topper, or 3 inch Talalay at 24 ILD if you sleep hot.
- Side sleeper over 230 pounds: 4 inch Gel Mattress Topper.
- Back sleeper who finds the bed too hard: 3 inch gel memory foam; 2 inches if you are under 130 pounds.
- Combination sleeper who tosses and turns: 24 ILD Talalay latex, which responds instantly when you move.
- Stomach sleeper: stay at 2 inches or choose the Tri-Zone; a deep soft topper lets the hips sag.
- Guest bed that is hotel-hard: 3 inch Gel Mattress Topper 2.0 with its washable cover.
Fit and first nights
A 3 inch topper on a 10 to 12 inch mattress needs fitted sheets with 15 inch or deeper pockets; a 4 inch topper needs 16 or more. Both raise the bed noticeably, so check headboard height and bunk rails. Memory foam ships compressed by FedEx Ground, arrives in 2-3 business days, and needs 24-48 hours to decompress; the 4 inch takes the longer end of that. Latex arrives ready to use. Give yourself a week to adjust, and if the feel is wrong, the 30-Night Happiness Guarantee covers a free return.

Questions about soft mattress topper
What is the softest mattress topper you make?
The 4 inch Gel Mattress Topper. Four inches of gel memory foam lets you sink fully into the surface, which is what heavier side sleepers and people with very firm mattresses are usually looking for. For a soft feel with bounce instead of sink, choose 24 ILD Talalay latex.
Will a soft mattress topper make my firm mattress feel plush?
Yes. Three inches of gel memory foam changes the surface of a firm hybrid or innerspring from hard to plush while the mattress keeps supporting you. Four inches goes further. If your mattress is firm because it is new, a topper also bridges the break-in period.
Can a soft topper cause back pain?
A poor one can, if it is so thin or low-density that the hips drop below the shoulders. Ours are dense enough to cushion without collapsing. Stomach sleepers are most at risk from deep soft toppers and should stay at 2 inches or use the zoned Tri-Zone.
Is memory foam or latex softer?
They are soft differently. Memory foam gives slowly and holds your shape, so it feels like sinking into the bed. 24 ILD Talalay latex yields at the surface but stays springy, so it feels plush yet you float on top. Hot sleepers and people who move a lot usually prefer latex.
How thick should a soft mattress topper be?
Three inches for most adults; it cushions the shoulder and hip fully. Four inches for sleepers over about 230 pounds or a mattress that is extremely firm. Two inches if you are under 130 pounds or only want a slightly softer surface.
Do soft memory foam toppers sleep hot?
Deep contouring holds more heat than a firm surface, which is why we gel-infuse our open-cell foam. Most sleepers find the 3 inch comfortable. If you run hot, a 24 ILD Talalay latex topper is the plush option that stays coolest.
Will a soft topper flatten out over time?
Fiber and low-density foam toppers do. Our gel memory foam is poured to a density that holds its loft, and Talalay latex is one of the most durable foams made. Every LOUNJ topper carries a 5-year warranty against defects, including permanent body impressions.
