Who is the LaComfort 14 Inch for?
The LaComfort 14 Inch suits sleepers who want a tall all-foam mattress with a medium firm feel, delivered as a bed-in-a-box, and priced well under $1,000. Dynasty Mattress lists it for general, stomach, back and side sleeper types, so the brand positions it as a single firmness option that covers most positions rather than a specialized model. If you want one firmness, one profile height, and a straightforward foam build, this is the shape of product you are looking at.
It is also aimed at practical buyers. Free shipping in the continental United States, a 30 year limited warranty, and CertiPUR-US certified foams are the three headline assurances the brand puts forward. The CertiPUR-US certification means the polyurethane foams have been tested for emissions, content, performance and durability, with low VOC emissions of less than 0.5 parts per million for indoor air quality.

The materials list is short and specific: a silk and polyester cover, breathable polyurethane foam, latex for durability, and gel-infused layers including 5 pounds of cooling gel. The comfort rating is Medium Firm, and the base option shown is mattress only.
How does the 14 inch build feel and support you?
At 14 inches, the brand describes the profile as combining breathable support with cooling gel technology for a temperature-regulated sleep. The comfort rating is Medium Firm, which is the middle-of-the-road territory that tends to suit back sleepers and combination sleepers who do not want either a deep hug or a rock-hard surface. Dynasty Mattress lists sleeper types as general, stomach, back and side, so the brand is not steering any position away from it.
The support story is foam-first. There is no coil unit in this mattress; the layers are polyurethane foam, latex and gel-infused foam. Latex is included specifically for durability, which matters on a 14-inch foam build where long-term shape retention is the usual concern. If you prefer the push-back of springs, this is a different category of mattress entirely, and the Saatva Classic pick above is the coil-based route.
What is the LaComfort 14 Inch made of and how does it cool?
Cooling is handled by gel infusion rather than by airflow channels or phase-change covers. The brand states the mattress includes 5 pounds of cooling gel across its gel-infused layers, paired with a breathable polyurethane foam layer and a silk and polyester cover. That is a gel-based cooling approach.
The CertiPUR-US certification covers the foam itself: tested for emissions, content, performance and durability, with VOC emissions under 0.5 parts per million. The cover material, silk and polyester, is the one soft-touch element in an otherwise functional material stack.

What does the LaComfort 14 Inch cost and what warranty comes with it?
The listed price on the Dynasty Mattress product page is $719.00, marked down from a $1,000.00 reference price. That figure is shown for the mattress as configured on the page, so check the current price before you order.
The warranty is a 30 year limited warranty, which applies to mattresses only. Adjustable bases carry a separate 10 year parts and labor warranty. Shipping is free for all products in the continental United States, unless otherwise prescribed. The brand also advertises fast delivery of 1 to 3 days and a mattress-in-a-box format, so the mattress arrives compressed and rolled rather than by scheduled freight.
Who should NOT buy the LaComfort 14 Inch?
Skip this mattress if you need a specific firmness rather than a single Medium Firm option. The product page shows one comfort rating across all sizes, so there is no softer or firmer variant to choose from. Sleepers who know they need Plush Soft or an extra-firm surface should look at brands that offer multiple firmness levels in the same model.
Also skip it if you want a trial period. The product page describes a 30 year limited warranty and free shipping, and does not present a home trial for this model. If a risk-free in-home trial is a requirement for your purchase, that changes the shortlist. Availability is another live factor: the page currently shows the Medium Firm configuration as sold out across several sizes, so confirm stock before building your plan around it.
Finally, sleepers who want the responsiveness and edge support of a coil system should not expect it here. This is an all-foam mattress, and the Saatva Classic above is the coil-based alternative with a 365-night home trial and a lifetime warranty.
How does it compare with the Saatva Classic?
The two mattresses sit in different construction categories. The LaComfort 14 Inch is an all-foam bed-in-a-box with gel-infused layers, a Medium Firm rating, a 30 year limited warranty, and a listed price of $719.00. The Saatva Classic is an innerspring mattress with a dual-coil design, a 3 inch Euro pillow top, three comfort levels, a 365-night home trial, free white-glove delivery with old mattress removal, and a lifetime warranty.
| LaComfort 14 Inch | Saatva Classic | |
|---|---|---|
| Construction | All-foam, gel-infused layers | Dual-coil innerspring with Euro pillow top |
| Height | 14 inches | 11.5 or 14.5 inches |
| Firmness options | Medium Firm | Plush Soft, Luxury Firm, Firm |
| Home trial | Not offered on the product page | 365 nights |
| Warranty | 30 year limited | Lifetime |
| Delivery | Free shipping, mattress in a box | Free white-glove setup and mattress removal |
Who should buy the LaComfort 14 Inch: It is a sensible pick for a guest room, a first apartment, or an RV, where the wide size range including RV King and RV Short King is genuinely useful. The 30 year limited warranty and CertiPUR-US certified foams give it a solid paper trail for the price.
Who should buy the Saatva Classic: shoppers who want a coil support system, multiple firmness choices, a full year to decide at home, and in-room delivery with their old mattress taken away. It is also the better fit for anyone who values chiropractor-approved lumbar support technology and a lifetime warranty over a lower entry price. The tradeoff is cost: the Saatva Classic is priced well above the LaComfort, so the budget gap between the two is the real decision point.
World Sleep Almanac score: 7.6/10. The editorial rating weighs five criteria: price at comparable size, trial and return terms, warranty length, materials and construction, and public customer feedback. The LaComfort scores well on warranty length at 30 years and on materials with CertiPUR-US certified foams, gel infusion and a silk blend cover, and it holds a competitive price at $719.00. It loses points because the product page offers no home trial and shows a single firmness option, and because stock is currently limited across sizes. The score is an editorial judgment based on these stated criteria, not a hands-on test result.
Verdict
The Dynasty Mattress Lacomfort 14 Inch Gel Memory Foam Bed is a strong budget buy for shoppers who want a tall, medium firm gel foam mattress and do not need a home trial. Buyers who want coils, multiple firmness levels and a year to decide should go with the Saatva Classic instead.

Frequently asked questions
Is the LaComfort 14 Inch a mattress in a box?
Yes. Dynasty Mattress lists the LaComfort under its mattress-in-a-box range, with fast delivery advertised at 1 to 3 days. The mattress arrives compressed and rolled in a box rather than by scheduled freight delivery, and free shipping is offered for all products in the continental United States.
What firmness is the LaComfort 14 Inch?
The comfort rating shown for this model is Medium Firm. It is a single firmness option across all sizes, so there is no softer or firmer version of the same mattress to choose between. Dynasty Mattress lists it for general, stomach, back and side sleeper types.
What is CertiPUR-US and why does it matter here?
CertiPUR-US means the polyurethane foams have been tested against standards for emissions, content, performance and durability. The foams are tested for low VOC emissions, under 0.5 parts per million for indoor air quality. On an all-foam mattress where foam makes up the entire build, that certification covers the material you spend the night on top of.
Does the LaComfort 14 Inch come with a home trial?
The product page presents a 30 year limited warranty and free shipping, and does not list a home trial for this model. If a trial period is important to you, that is a meaningful difference from brands that include one, and it is worth confirming directly with Dynasty Mattress before ordering.
Which sizes does the LaComfort 14 Inch come in?
The size range is unusually wide: Twin, Twin XL, Full, Full XL, Queen, King, Cal-King, Split King, Split CalKing, Split Head King, RV King and RV Short King. The RV-specific sizes and the split options make it a practical choice for non-standard bed frames and adjustable bases where a standard Queen or King will not fit.
