The Restonic ComfortCare QR Waldorf ET is built around one clear promise: a cooler night’s sleep, achieved through a stack of cooling foams sitting above an individually wrapped coil unit. If you tend to sleep warm and you share a bed, this ComfortCare model puts its stated technology where it matters, at the surface and through the support core. Restonic names each layer and what it does, which makes the construction easy to follow before you ever see the mattress in a showroom.

Who is the ComfortCare QR Waldorf ET for?
The ComfortCare QR Waldorf ET suits sleepers who overheat at night and who want that cooling built into named layers rather than added as a cover gimmick. It also suits couples, because the coil unit carries Restonic’s Marvelous Middle design, which the brand states prevents motion transfer between partners. Shoppers who want a stated firmness choice, a long home trial or white-glove setup will find those decisions belong to other brands and other models.
Who should buy it, and who should not: the QR Waldorf ET is for heat-sensitive sleepers who are comfortable buying through retailers that set their own trial and return terms, and who value a mattress with a named lumbar support layer. It is not for shoppers who insist on a 365-night trial and a lifetime warranty written into the purchase, because those terms come from Saatva, not from this Restonic product page.
What goes inside the ComfortCare QR Waldorf ET?
The build reads as a cooling stack over a wrapped coil core, with a dedicated lumbar layer in between. Each element has a stated job, and together they describe a mattress that moves heat away, cushions the body, supports the lower back and keeps partners from disturbing each other.
- Cooling Technology creates a cooling effect by gently moving heat away from your body for a temperature-controlled micro-climate.
- CoolComfort Gel Foam provides optimal surface cooling, cushioning and conformability.
- CoolFlow Plush Foam equalizes pressure distribution with extra cushioning while enhanced breathability helps with temperature regulation.
- TempaGel by Restonic is a gel-infused memory foam that delivers the contouring support of memory foam with gel that dissipates heat instead of storing it.
- 800 Series Individually Wrapped Coil Unit features the exclusive Marvelous Middle and prevents motion transfer between partners.
How does the cooling setup actually work?
Restonic describes a three-stage approach: heat is gently moved away from the body, the surface stays cool through gel foam, and breathability in the plush foam layer helps regulate temperature. The TempaGel memory foam adds a fourth angle, since its gel dissipates heat rather than storing it. This is a layered strategy rather than a single feature, which is worth knowing if you have tried one-coil or one-foam cooling mattresses before.
The lumbar support gel-infused memory foam sits in the same family of materials, delivering contouring support while its gel works on heat at the same time. Restonic’s language here is consistent: cooling is handled at the surface and again in the comfort layers, not just in one place.
What does the construction mean for feel and support?
The comfort layers point toward a cushioned, conforming feel rather than a hard, flat top. CoolComfort Gel Foam is specified for cushioning and conformability, CoolFlow Plush Foam for equalized pressure distribution, and TempaGel for contouring memory foam support. Underneath, the 800 Series wrapped coil unit provides the spring support, with the Marvelous Middle design focused on the center of the mattress where body weight concentrates.
For support, the stated lumbar layer is the element to watch. Restonic calls it Lumbar Support and describes it as gel-infused memory foam delivering contouring support. Shoppers who need extra attention at the lower back should ask their retailer how this layer is positioned in the QR Waldorf ET configuration.
What do verified buyers say about ComfortCare?
Restonic’s site carries verified buyer reviews tagged to the ComfortCare collection, and the tone is positive on support and comfort. One buyer rated 4 out of 5 and wrote that the mattress is very supportive with just the right amount of foam to coil. Another rated 5 out of 5 and reported buying a king size Restonic mattress 8 to 10 years earlier. A third rated 5 out of 5 and said the sleep had been the best in years after shopping for about a year. A 2021 review rated 4 out of 5 and called it the best they had slept in years.
These are collection-level reviews rather than QR Waldorf ET specific ones, so treat them as a signal about the ComfortCare line rather than a verdict on this exact layer stack.

How does it compare with other Restonic ComfortCare models?
The ComfortCare line offers several configurations, and the differences are in the coil count and the specific comfort materials rather than in the brand’s overall approach. The table below sets out what Restonic states for each, so you can see where the QR Waldorf ET sits.
| Model | Cooling or comfort materials | Support core |
|---|---|---|
| QR Waldorf ET | Cooling Technology, CoolComfort Gel Foam, CoolFlow Plush Foam, TempaGel | 800 Series wrapped coil unit with Marvelous Middle |
| Adorn ET | Dual Cooling Technology, CoolComfort Gel Foam, DuraLast Support Foam, Air Suspension Foam | 800 Series wrapped coil unit with Marvelous Middle |
| Enchantment Hybrid | Dual Cooling Technology, copper infused latex, TempaGel, DuraLast Support Foam | 1,000 Series wrapped coil unit with Marvelous Middle |
| Fantasy Hybrid | Dual Cooling Technology, TempaGel, copper infused latex, 1,300 Series MicroCoil | 1,000 Series wrapped coil unit with Marvelous Middle |
Read the individual reviews for the full picture: the ComfortCare Adorn ET, the ComfortCare Enchantment Hybrid and the ComfortCare Fantasy Hybrid each carry their own layer stack and stated benefits.
Who should NOT buy the ComfortCare QR Waldorf ET?
Skip this model if a long home trial and a written lifetime warranty are non-negotiable for you, since the Restonic product page states neither. Skip it too if you want a firmness choice at the point of purchase, because the QR Waldorf ET is presented as a single configuration. And if you want a genuinely hard, flat surface rather than a cushioned one, the ComfortCare line has firmer options, including the ComfortCare Dynasty Firm.
The QR Waldorf ET is a better match for shoppers who prioritize cooling layers and lumbar contouring, and who are content to set trial and warranty terms with the retailer that sells it.
What is the Saatva alternative?
The Saatva Classic is the innerspring alternative if you want choice written into the purchase. It comes in three comfort levels, Plush Soft rated 3 out of 10, Luxury Firm rated 5 to 7 out of 10, and Firm rated 8 out of 10, and in two heights, 11.5 inches and 14.5 inches. It carries a 365-night home trial, free white-glove delivery with in-room setup and old-mattress removal, and a lifetime warranty for the original purchaser.
The construction is a 3 inch Euro pillow top over a dual-coil design of triple-tempered recycled carbon steel, with patented Lumbar Zone Technology for spinal alignment and a breathable organic cotton cover. Certifications include CertiPUR-US certified foams and GREENGUARD Gold certification, and the mattress is endorsed by the American Chiropractic Association. The key difference from the QR Waldorf ET is the trial and warranty package: 365 nights and a lifetime warranty versus retailer-set terms.
Verdict: the Restonic ComfortCare QR Waldorf ET is the pick for heat-sensitive sleepers who want named cooling layers and a lumbar support foam, and who are happy to buy through a retailer that sets its own trial terms. Shoppers who want a firmness choice, a 365-night trial and a lifetime warranty should look at the Saatva Classic instead.
Verdict
Buy the QR Waldorf ET for its cooling stack and lumbar layer. Buy the Saatva Classic for choice, a 365-night trial and a lifetime warranty.
