The 30-second verdict
No, most buyers should pass on the Novaform SoFresh Plus 10” Responsive Foam Mattress. NapLab's main concern is early sagging and body impressions. For a budget-focused side sleeper, the Siena 10-inch Signature Memory Foam Mattress is a better-fit pick: Sleep Foundation gives it a 7.5 overall test lab score, and its Queen price is $329. Buy it only if you are comfortable with that risk and want an all-foam mattress.

Sizes4Twin to King
Pros
Removable cover. Costco lists a removable, machine-washable moisture-wicking cover.
Foam certification. Novaform says its CertiPUR-US® certified foam has no heavy metals or phthalates, low VOCs, and no ozone depleters.
Flat rotation. Novaform recommends occasional flat rotation, so you do not need to flip it.
Cons
Edge support. NapLab rates lying edge support fair, so the edge may feel less steady when you sleep near it.
Surface temperature. NapLab measured a maximum surface temperature of 90.7° F, a result hot sleepers may want to weigh.
Split firmness. Costco calls it medium; NapLab rates it medium-firm, 6 out of 10, making the feel less clear.
How firm is the SoFresh Plus 10″ Responsive Foam Mattress, and which firmness should you pick?
Choose the listed Medium option if that label matches the feel you want; NapLab rates the mattress Medium-Firm, 6 out of 10 on its scale. NapLab updated the reading June 11, 2026. The listing and outside result use different terms, so compare them with your firmness preference before buying. The option name shows what you can select; the tester's score gives another way to judge the feel. Let the description that best fits your target guide your choice rather than guessing from the name alone.

Tester readings
How outside testers rate its firmness
Every tester uses its own scale, so each reading is shown as that tester wrote it.
Is the SoFresh Plus 10″ Responsive Foam Mattress right for your sleep position and body weight?
Yes, NapLab marks this bed as a fit for side, back, and stomach sleepers under 150 lbs. Combination sleepers who rotate among those positions can use the ratings as a relevant fit signal. Check that your usual positions and weight band match before treating the guidance as a reason to choose it.
NapLab rates edge support as good while sitting and fair while lying down. If you sleep near the mattress edge, give the lying result more weight in your decision. The sitting result matters more if you often sit at the edge to get dressed or put on shoes. Match the edge rating to how you use the mattress, then balance that trade-off against its fit for your sleep position.

Edges
Edge support, outside tester
Good sitting edge support and fair lying edge support (NapLab).
Neck: lying on your side, ask if your pillow and the bed keep your head in line with your spine.
Shoulders: ask if the shoulder under you settles in, or if you feel a pinch after a few minutes.
Back: lying face up, slide a hand under your waist. A big gap or no room at all is a sign of a poor match.
Hips: ask if your hips dip lower than your shoulders, like lying in a shallow bowl.
Four checks: lie still for a few minutes in the position you sleep in most, then notice how each spot feels. These are comfort checks, not a medical test.Sources (1)
Is the SoFresh Plus 10″ Responsive Foam Mattress good for back pain?
The SoFresh Plus may interest back sleepers, but its support claims are not a promise of pain relief. The brand says its premium memory foam offers pressure-relieving support. NapLab's back-sleeper pressure map recorded average pressure of 0.06 PSI and maximum pressure of 0.50 PSI. PSI measures pressure, so use these figures as test readings, not as a pain score when weighing the mattress.

Ongoing back pain? Ask a doctor or physical therapist what support your back needs before you buy.
NapLab measured a maximum surface temperature of 90.7° F, but that reading alone does not say whether the mattress sleeps warm or neutral. Its listed cooling features are a removable, machine-washable moisture-wicking cover, copper-infused foam, and responsive LURAcor™ foam. These give you the specific cover and foams to look for, but treat the temperature as a measurement, not a promise of a cool night.
You may feel a restless partner move, but these readings cannot predict whether they will wake you. NapLab measured motion transfer: 10.94 m/s² acceleration range and 0.72-second duration. Bounce was 7.22 in total, with 5.15 in max depth and 2.07 in max rebound. For a light sleeper, treat partner movement as a possible disturbance, not something these readings show the mattress will block.

The cover is polyester, and CertiPUR-US® covers the mattress foam, not the whole bed. The top is 100% polyester; the border is 95% polyester, 3.5% viscose, and 1.5% spandex. Novaform says its certified foam contains no heavy metals, no phthalates, low VOCs, and no ozone depleters. That scope matters if you want certification to cover more than the foam.
Does the SoFresh Plus 10″ Responsive Foam Mattress have fiberglass?
Novaform says both the mattress and cover are fiberglass free. Check the law tag on your mattress to see the listed materials and confirm what its fire barrier is made from. The tag gives you a materials list to review when deciding whether this bed meets your needs, rather than relying on the maker's statement alone.
The brand says this mattress works with platform beds, standard box springs, and adjustable bases. The base must provide proper airflow and support. If it uses slats, they must be spaced less than six inches apart. The limited warranty may be void if the base lacks airflow or support, or if its slats miss that spacing rule. Check your adjustable base for these requirements before buying.

How long will it last, and does it need flipping or rotating?
NapLab says lower-quality foams tend to sag deeper and earlier, and names early sagging and body impressions as its chief concern for this mattress. Novaform says it can take up to 1-2 weeks to get used to the new feel, especially if you usually sleep on a standard spring mattress. For care, Novaform recommends occasional flat rotation and says not to flip it.
The brand gives this bed a 5 - 7 business day wait window; confirm setup and old mattress removal before ordering. That range can guide when you prepare the room and plan around your current mattress. Check the order details for what delivery includes, then schedule any work that depends on setup or removal accordingly.
Novaform lists a 20-year limited warranty for this mattress. For your decision, treat that figure as the warranty's length, not a sag threshold. Read the warranty terms before relying on coverage or filing a claim, so you can check the conditions and steps that apply to your situation.
How does the SoFresh Plus 10″ Responsive Foam Mattress compare?
The SoFresh Plus has Novaform alternatives for different support and height needs, plus two all-foam rivals.

Pick Legacy Elite Premier for a taller, 16-inch medium-firm design, or Legacy Premier Support for a firmer feel. ComfortGrande Advanced Hybrid is for responsive coils and firm edge foam. Choose ComfortGrande Advanced for triple-action cooling. Novaform describes Serafina PerfectTemp as its cooling model with dual phase change material. Advanced Back Support Plus offers targeted back support from contoured foam. DreamAway is the shorter, 8-inch choice.
For an all-foam memory foam feel, consider Saatva Loom & Leaf; Sleep Foundation gives it a 9.1 overall rating. Siena 10-inch Signature Memory Foam Mattress is a budget all-foam option for side sleepers, with a Queen price of $329. Sleep Foundation's 10-inch review gives it a 7.5 overall test lab score.
