Bed to Bed: Simmons Curv vs. Serta iComfort

Continuing our Bed to Bed comparison series, today we look at two memory foam lines, Simmons Curv and Serta iComfort. For each brand, we collected manufacturer information and bed specifications, and as well as reports from owner reviews. The comparison highlights how Simmons Curv and Serta iComfort compare in terms of value and performance on leading factors of concern for mattress shoppers.

The Brands

Both Simmons and Serta are well-known in the mattress industry, having established themselves first as innerspring brands and recently branching out into memory foam. Both Simmons and Serta are currently owned by the same parent company, but operate as two separate brands.

Simmons Curv

Simmons entered the mattress business in 1876, initially making their name with wire and spring beds which still constitute the bulk of their sales. They introduced the Simmons Curv memory foam mattress line in 2013, with an eye on reaching the Millennial consumer segment which has shown a preference for memory foam but is typically priced out of the luxury market. The surface layer of the memory foam beds have a rippled appearance, which is described as facilitating air flow. The mattresses are made of traditional and gel memory foam with CertiPUR certification, and priced under $999.

The Simmons Curv lineup includes three models:

NameProfile HeightMemory Foam LayersPrice/Queen Set
The Latest Thing8"1.5” 2lb density memory foam$699
All The Rage9"2.5” 2lb density memory foam with gel$799
Vogue10..5"1” 2lb density memory foam with gel,
2.5” 3lb density memory foam

Serta iComfort

Serta has been in business since 1931 as a spring mattress manufacturer, and introduced their iComfort line in 2011. Serta iComfort beds feature gel-infused memory foam combined with traditional memory foam. The brand claims that the introduction of gel offers cooler sleep than traditional brands like Tempurpedic, but has faced some pushback regarding these claims. Pricing begins around $1000 and goes up to $3000.

The Serta iComfort lineup includes six core models:

Comparing Simmons Curv and Serta iComfort Mattresses

Simmons Curv and Serta iComfort are both memory foam mattress lines. Simmons is targeting the low to mid range price segment, while Serta targets the mid- to high range segment. Both brands are made in USA, and sold through large dealer networks. Keep reading to see how the specifications stack up.

Quality & Density

Serta iComfort beds have memory foam layers that vary between 3.0 and 5.0 lbs. Simmons Curv uses 2.0 lb foam in all models, with the more expensive Vogue also containing a 3.0 lb foam layer. On average, the Curv beds have slightly less memory foam in their profiles and lower densities by 1-2lb compared to iComfort, but cost up 37-46% less.  However, the 2.0 lb memory foam used in the Curv line is considered very low density, and low density foams are less resistant to impressions over time and provide less buoyant support than medium and high density foams. Low density foams do, however, cost less to produce, tend to retain less heat, and also have less odor.

Pricing and Costs

The price for a Simmons Curv queen-sized mattress set varies from $699 – $999 depending on the model, but may be lower depending on dealer sales. Serta iComfort beds have manufacturer-fixed prices ranging from $1299- $2999 for queen sized mattress sets

For a more direct contrast, the Simmons Curv The Latest Thing and Serta iComfort Insight are both 8” beds, with The Latest Thing featuring 1.5” of 2lb memory foam  for around $699 and the Insight featuring 2.75” of 4lb memory foam for around $1299.  For the brands’ 10 models, the Curv  Vogue contains 3.5” of 2 and 3lb memory foam for $999, while the Genius contains 2.75” of 4lb memory foam for $1599. The Curv line currently does not include models  that compare to the higher end range of the iComfort line.


Both brands have similar constructions, with poly foam cores providing support and varying thicknesses of memory foam providing comfort. Neither brand publishes information on mattress core density, so it is difficult to compare them in this regard. Both brands also use “knit fabric” covers with various designs.

Responsiveness & Pain Relief

The responsiveness of a memory foam refers to how quickly it returns to its original shape or recontours. Low density foams tend to recontour more quickly, so it is likely that Simmons Curv will remold quicker and feel easier to move on than the denser iComfort models.

Memory foam in general excels at pain relief, so both options should offer moderate comfort. The medium density in iComfort (4.0-5.0 lbs) may provide better pressure relief than the lower density foams (3.0 lbs and lower). The Curv models, especially those with less than 3” of memory foam, may not provide sufficient pressure and pain relief for side sleepers or larger individuals.

Sleeping Hot

About 10% of all memory foam mattress owners complain that their beds trap heat or make them feel too hot at night. Both brands have features they claim help their beds sleep cooler, from Simmons’ curved memory foam to iComfort’s gel infused layers. Generally, lower density foams retain less heat, and gel has only been shown to provide moderate cooling initially (eventually the gel acclimates to body temperature). About 4-6% of reviews for Serta iComfort reviews complain of heat, which is lower than average. Simmons Curv is still too new, and there are no owner reports available yet. However, with the lower density and thinner layers of memory foam, it is likely that it too will have lower than average heat complaints.

Off-gassing and Odor

Off-gassing and odor can be another issue for memory foam mattresses, with up to 15% of people reporting strong odors. About 6-8% of iComfort owners mention odors or offgassing, though Serta claims they do not use harmful chemicals in production. Again, Curv is too new to gather owner data, however the foams are CertiPur certified and their low density means off-gassing is likely to be minimal.


Simmons Curv offers customers a 10-year limited warranty covering impressions over 1.5”. Serta offers a 25-year warranty, with 15 years full coverage and the remaining 10 years prorated, covering impressions over 0.75”. Serta iComfort also comes with a 120 day trial period, whereas Curv trial periods appear to depend on the retailer.

Durability and Longevity

Based on memory foam industry averages, most people use their mattress for 5-10 years. Simmons Curv has not been on the market long enough to ascertain its longevity, but based on other mattresses using low density memory foam, it will likely be in the 5-6 year range. Serta iComfort owners report higher than average issues with impressions in the first few years, but are expected to last around 8-9 years.

Overall Owner Satisfaction

We could not find any Simmons Curv reviews thus far, however the mattress line has only been available for a couple of months.  The Serta iComfort line has been out since 2011, and it has an average owner rating of about 4.1 / 5 or 80-82%. Serta iComfort rates slightly above average compared to memory foam in general, but below other comparable brands.

Overview of Simmons Curv vs. Serta iComfort

The main factors to consider when comparing these two mattress brands include the memory foam layers, guarantees and overall value. Simmons Curv uses lower density foam than most iComfort models, however it is also considerably cheaper, which may be more important for some shoppers. The iComfort is likely to outlast the Curv in terms of durability, and also comes with stronger warranties and guarantees. On the other hand, consumers will have to make the decision as to what “value” means to them, and whether or not the slight increase in density and warranty coverage is worth the more expensive price, in addition to comparing each brand to other options in the marketplace.

Stay tuned! As more owner review information becomes available for the Simmons Curv line in coming months, we plan on updating our comparison to provide a more complete picture.
