Quick Answer
Memory foam mattresses at Costco (Novaform, Casper, Sealy) are all-foam, ranging from $400 to $900 for a queen, with zero coils. They rely entirely on foam layers for both comfort and support. This leads to faster wear, body impressions, and heat retention. You get the pressure relief of memory foam with the structural support of a coil system. Hand-tufted, Canadian-made, with a 10 to 15 year lifespan versus 4 to 6 years for all-foam.
Brad, Owner, 40+ years of experience: "We have been helping Brantford families sleep better since 1997. Every customer gets personal attention, honest advice, and the kind of follow-up service you just do not get from big box stores."
Shopping for a memory foam mattress at Costco? The boxes are stacked high, the prices are low, and the names sound impressive: Novaform ComfortGrande, Casper Element, Sealy Essentials Memory Foam. But before you load one into your cart, ask yourself this: what is underneath that memory foam?
The answer, in every case, is more foam. No coils. No springs. No support structure at all. Just layers of foam of varying density, compressed into a box. The memory foam you feel on top is comfortable. The problem is what is not below it.
We are Brad, Dorothy, and Talia at Mattress Miracle in Brantford, Ontario. We have been fitting people to mattresses for 37 years. Memory foam is an excellent comfort material. We use it ourselves: every Restonic ComfortCare mattress in our showroom has a TempaGel gel-infused memory foam comfort layer on top of 1,222 individually wrapped pocket coils. The difference is that we use memory foam where it belongs: as a comfort layer, not as the entire mattress.
What's in This Guide
The Foam-Only Problem
Memory foam was invented by NASA in 1966 to improve seat cushioning for astronauts. It became popular in mattresses because it conforms to body curves and relieves pressure points. Those qualities are real. Memory foam does contour to your body. The question is what happens beneath that contouring layer.
In a Costco memory foam mattress, the answer is: more foam. A high-density polyurethane foam base, usually 5 to 7 inches thick, sits underneath the memory foam comfort layer. This foam base is the support structure. There is nothing else. No springs, no coils, no mechanical system to push back against your body weight.
What Happens to Foam-Only Support Over Time
Month 1 to 6: The foam feels supportive. Your body sinks into the memory foam comfort layer and the base foam holds you up. Everything seems fine.
Month 6 to 18: The base foam begins compressing in the areas where your body exerts the most pressure: hips and shoulders. It does not spring back the way a coil would. Foam compression is gradual and permanent.
Year 2 to 4: Visible body impressions develop. Your hip area sinks deeper than the surrounding surface. Your spine is no longer aligned. You start waking up with back stiffness or hip pain that was not there before.
Year 4 to 6: The mattress is functionally worn out. The memory foam comfort layer is still technically working, but it is conforming to a support base that has already lost its shape. You are sleeping in a foam valley.
A pocket coil system solves this problem mechanically. Each coil is a steel spring that returns to its original shape every single morning. The 1,222 pocket coils in a Restonic ComfortCare queen have been engineered to maintain their spring tension for 10 to 15 years. The TempaGel memory foam comfort layer on top provides the same pressure relief as a Costco memory foam mattress, but it does not have to do double duty as both comfort and support.
Memory Foam Options at Costco
Costco rotates its memory foam mattress selection seasonally, but the lineup typically includes these brands:
Typical Costco Memory Foam Mattresses (Queen Size)
| Brand/Model | Price Range | Construction | Coils |
|---|---|---|---|
| Novaform ComfortGrande | $500 to $700 | All-foam (gel memory foam + poly base) | Zero |
| Novaform DreamAway | $400 to $500 | All-foam (memory foam + poly base) | Zero |
| Casper Element | $500 to $700 | All-foam (memory foam + poly base) | Zero |
| Sealy Essentials Memory Foam | $600 to $800 | All-foam (memory foam + poly base) | Zero |
| Blackstone Cerazone | $400 to $600 | All-foam (copper-infused foam + poly base) | Zero |
↔ Scroll to see full table
Notice the pattern: every option is all-foam. Zero coils. The price differences reflect foam density, thickness, and cooling features, not structural support differences.
These are functional mattresses at low price points. The problem is not that they are bad mattresses on day one. The problem is what they become by year three.
Foam-Only vs Foam-Plus-Coils: A Direct Comparison
The simplest way to understand the difference is to look at what each mattress contains from top to bottom:
Construction Comparison (Queen Size)
| Layer | Costco Memory Foam | Restonic ComfortCare |
|---|---|---|
| Top Comfort | 2 to 3" gel memory foam | TempaGel gel-infused memory foam |
| Transition | 1 to 2" transition foam | High-density foam |
| Support Core | 5 to 7" polyurethane foam | 1,222 individually wrapped pocket coils (Marvelous Middle zoned) |
| Edge Support | None (foam compresses at edges) | SuperEdge Plus foam encasement (full perimeter) |
| Construction | Adhesive-bonded layers | Hand-tufted (ribbons bind all layers) |
| Manufacturing | Imported, compressed in a box | Canadian-made |
↔ Scroll to see full table
Both mattresses have memory foam comfort layers. Only one has a structural support system underneath. That support system is the difference between a mattress that lasts 4 to 6 years and one that lasts 10 to 15.
Brad's Take on Memory Foam
"Memory foam is a great material. I am not against memory foam at all. Every Restonic ComfortCare in our showroom has TempaGel gel-infused memory foam. The issue is when memory foam is asked to do a job it was never designed for. Memory foam was invented to cushion. It was not invented to support. When you put 150 or 200 pounds on a foam base every night for years, the foam compresses. It has no mechanism to push back. A steel coil does. That is why you want foam on top and coils underneath."
The Heat Trap Nobody Talks About
Every memory foam mattress at Costco advertises some form of cooling technology: gel-infused, copper-infused, ventilated, charcoal-infused. These features are real, and they help. But they are working against a fundamental physics problem.
Memory foam is a dense, solid material. There are no air channels running through it. When your body radiates heat into the foam, that heat has nowhere to go except to be stored in the surrounding foam and radiated back to you. Gel infusion helps for about the first 30 to 60 minutes by absorbing excess heat. After that, the gel itself reaches equilibrium and stops cooling.
A pocket coil system creates natural ventilation. Each of the 1,222 coils in a Restonic ComfortCare queen is individually wrapped, creating hundreds of air channels throughout the mattress core. Warm air rises through these channels and dissipates naturally. Combined with the TempaGel comfort layer on top, you get active heat dissipation from the foam AND passive ventilation from the coil system.
Talia explains what hot sleepers often discover: "We get customers every summer who bought memory foam mattresses thinking the gel infusion would keep them cool. It helps for the first little while, then the mattress heats up and holds onto it. When they lie on the ComfortCare in our showroom, the first thing they notice is that the coil system breathes. Air actually moves through the mattress. Combined with the TempaGel, it is a completely different sleeping temperature."
How Long Does Each Really Last?
Realistic Lifespan Comparison
| Factor | Costco Memory Foam | Restonic ComfortCare |
|---|---|---|
| Body impressions begin | 6 to 18 months | Rare within warranty period |
| Noticeable support loss | Year 2 to 3 | Year 8 to 10 |
| Functionally worn out | Year 4 to 6 | Year 10 to 15 |
| Can you flip it? | No (single-sided) | No (but higher-tier Restonic models are flippable) |
| Edge support lifespan | Edges compress within months | SuperEdge Plus maintains perimeter for life |
↔ Scroll to see full table
The reason for the lifespan difference is mechanical. Steel coils have engineered tension that holds for 10 to 15 years. Foam compression is permanent. Once foam compresses, it stays compressed. No amount of rotating will restore the original support.
Cost Per Year: The Real Comparison
The sticker price on a Costco memory foam mattress looks like a clear win. The cost-per-year calculation tells a different story.
Queen Size: Cost Per Year of Sleep
| Mattress | Price | Lifespan | Cost/Year |
|---|---|---|---|
| Novaform DreamAway | $450 | 4 to 5 years | $90 to $113/year |
| Novaform ComfortGrande | $650 | 4 to 6 years | $108 to $163/year |
| Casper Element | $700 | 4 to 6 years | $117 to $175/year |
| Sealy Essentials Memory Foam | $750 | 5 to 6 years | $125 to $150/year |
| Restonic ComfortCare | $1,125 | 10 to 15 years | $75 to $113/year |
↔ Scroll to see full table
The Restonic ComfortCare ties or beats every Costco memory foam mattress on cost per year. And during those 10 to 15 years, you are sleeping on a mattress with functioning support, not one with permanent body impressions.
Why Fitting Matters More Than Foam Type
Here is the part that surprises most people: the type of foam in your mattress matters less than whether the mattress is properly matched to your body.
At Costco, you choose a memory foam mattress based on the price, the label, and maybe a 30-second press through the plastic wrapping. Nobody asks about your sleeping position. Nobody considers your body weight, your partner's weight, or whether you have lower back issues. Nobody explains that a side sleeper at 130 pounds and a back sleeper at 220 pounds need completely different support levels.
At Mattress Miracle, the fitting is the entire point. Brad, Dorothy, or Talia will spend 20 minutes understanding how you sleep before recommending a single mattress. They will have you lie on multiple models in your natural sleeping position. They will explain the difference between the Dalton (Firm) and Albany (Plush) options in the ComfortCare line, and whether your body weight and sleep position call for firm, plush, or the split comfort option.
Dorothy describes what proper fitting prevents: "We see people come in who have been sleeping on memory foam for three years with back pain, and they thought the foam was supposed to fix it. The foam is fine. The firmness was wrong for their body. A 140-pound side sleeper on a firm memory foam mattress will feel pressure on the hips and shoulders because the foam is too resistant. The same person on a plush mattress with the right coil support will have their spine aligned properly. No amount of foam quality fixes a bad firmness match."
The Full Restonic Lineup (Queen Pricing)
- ComfortCare (Dalton/Albany): $1,619 queen, 1,222 pocket coils, TempaGel, SuperEdge Plus. Details

FAQs: Memory Foam Mattresses at Costco
Are memory foam mattresses at Costco good quality?
The foam itself is acceptable quality. The issue is construction: all-foam mattresses with zero coils rely entirely on foam for support, which compresses permanently over time. A better approach is memory foam as a comfort layer on top of pocket coils, combining the pressure relief of foam with structural coil support.
How long do Costco memory foam mattresses last?
Most all-foam memory foam mattresses last 4 to 6 years before developing permanent body impressions. A pocket coil mattress with memory foam comfort layers lasts 10 to 15 years because the coils maintain their shape.
Do memory foam mattresses sleep hot?
Yes. All-foam mattresses trap body heat because the dense foam has no air channels. Gel infusion helps for the first 30 to 60 minutes, then reaches equilibrium. Pocket coil mattresses allow air to circulate between the coils, providing consistent temperature regulation throughout the night.
What is better than a memory foam mattress from Costco?
A pocket coil mattress with memory foam comfort layers gives you the pressure relief of foam with the structural support of coils. The Restonic ComfortCare queen has 1,222 pocket coils plus TempaGel gel-infused memory foam for $1,619 at Mattress Miracle, Canadian-made with hand-tufted construction.
Can I try a memory foam mattress before buying at Costco?
Most memory foam mattresses at Costco are sold compressed in boxes. You cannot test them in your sleeping position before purchasing. At Mattress Miracle in Brantford, you can lie on every mattress in the showroom and receive expert fitting from Brad, Dorothy, or Talia.

Are memory foam mattresses at Costco good quality?
Costco memory foam mattresses like Novaform and Casper use decent foam but rely entirely on foam for support with zero coils. This means faster wear, body impressions within 2-4 years, and heat retention. A better approach is memory foam as a comfort layer on top of a pocket coil system, like the Restonic ComfortCare at Mattress Miracle.
How long do Costco memory foam mattresses last?
Most all-foam memory foam mattresses from Costco last 4 to 6 years before developing permanent body impressions and losing support. By comparison, a pocket coil mattress with memory foam comfort layers, like the Restonic ComfortCare, lasts 10 to 15 years because the coil system maintains its structure.
Do memory foam mattresses sleep hot?
Yes. All-foam memory foam mattresses trap body heat because dense foam has no air channels. Even gel-infused foam only helps for the first hour. Pocket coil mattresses allow air to circulate between the coils, combined with cooling materials like TempaGel, for consistent temperature regulation throughout the night.
