Sweetnight CoolNest vs Tempur-Pedic: Which Should You Buy?

The Sweetnight CoolNest Hybrid and Tempur-Pedic take two different routes to a comfortable night. The CoolNest Hybrid builds its comfort from gel-infused memory foam, high resilience foam and pocket coils, with three thickness options at 12, 14 and 16 inches. Tempur-Pedic builds its comfort from TEMPUR-Material, which the brand says adapts to your body’s weight, shape and temperature. Neither mattress is sold by Saatva, so this page compares the two head to head and then offers the Saatva Classic as a strong alternative for readers who want a different construction and a longer trial.

Who should buy the Sweetnight CoolNest Hybrid: shoppers who want a hybrid with a cooling cover, a pillow top and a 100-night trial at a mid-range price. Who should buy Tempur-Pedic: sleepers who want a material that adapts to body shape and temperature, white glove delivery with old bed removal, and a 90-night trial. Who should not buy either: anyone who wants the longest home trial and a lifetime warranty, because both of these brands list a 10-year warranty, and the Saatva Classic fixes that with a 365-night home trial and a lifetime warranty.

What is the Sweetnight CoolNest Hybrid?

The Sweetnight CoolNest Hybrid is a hybrid mattress sold with a 100-night trial, a 10-year limited warranty and free U.S. shipping. It comes in three thicknesses: 12 inch Essential Cooling, 14 inch Enhanced Cooling and 16 inch Ultimate Cooling and Support. The brand lists the Queen price at $499.99 with a comparison value of $666.99, and the mattress ships in 1 to 2 business days.

The construction runs in nine layers. The comfort pillow top starts with a cooling ice silk cover, gel-infused memory foam and plush comfort foam. Deep cooling layers add gel-infused memory foam and PCMflux high resilience foam. Support comes from high-density support foam, a zoned support foam on the 14 and 16 inch models only, and Innovative Dynamic Coil technology made of high-compression pocket coils with a reinforced edge. A wear-resistant base layer closes the stack. Sweetnight states that all its foam is CertiPUR-US certified and that the CoolNest Hybrid fabric is certified to OEKO-TEX Standard 100.

What is Tempur-Pedic?

Tempur-Pedic is a mattress brand built around TEMPUR-Material, which the brand says adapts to your body’s weight, shape and temperature to relieve pressure points and reduce motion transfer. Tempur-Pedic offers Soft, Medium Hybrid, Medium and Firm feels across its current mattresses. A mattress bought directly from Tempur-Pedic carries a 90-night trial, a 10-year limited warranty and complimentary white glove delivery with setup and old bed removal.

The brand lists several models on its mattress page, including the TEMPUR-Cloud, TEMPUR-Adapt Medium, TEMPUR-ProBreeze Medium and TEMPUR-ActiveBreeze Smart Bed. Prices on that page are shown as a list price next to a promotional price, so this page does not quote them as settled figures. Tempur-Pedic also lists 0 percent APR financing for 36 months on select purchases, with no annual fee.

How do the two mattresses compare side by side?

This table lines up what each brand publishes about its own mattress.

Which mattress feels better for side and back sleepers?

Side and back sleepers should start with the feel each brand states. Tempur-Pedic publishes four feels, Soft, Medium, Medium Hybrid and Firm, so a side sleeper can start with Soft and a back sleeper with Medium.

The CoolNest Hybrid places a DuoSense pillow top above gel-infused memory foam, which gives a cushioned surface before the coils take over. The zoned support foam appears only on the 14 and 16 inch models, so a shopper who wants that layer should choose one of those two thicknesses. Tempur-Pedic describes its material as responding through a viscous response that absorbs the force of your body and its pressure points.

Which mattress is better for hot sleepers?

Both brands address heat in their own way. Sweetnight builds the CoolNest Hybrid around a multi-stage cooling system: an ice silk cover, gel-infused memory foam and PCMflux high resilience foam, with the brand labeling the 16 inch model Ultimate Cooling and Support. Tempur-Pedic lists the TEMPUR-ProBreeze Medium as feeling up to 10 degrees cooler all night, and the TEMPUR-ActiveBreeze Smart Bed as offering a sleep temperature range of up to 30 degrees warmer or cooler.

Those Tempur-Pedic cooling figures belong to specific models, not to every mattress the brand sells. A shopper comparing the two should read the model name next to the claim before assuming it applies to the version in the cart.

How do materials and certifications differ?

Sweetnight publishes its certifications on the CoolNest Hybrid page: all foam is CertiPUR-US certified and the fabric is certified to OEKO-TEX Standard 100. The layer list names gel-infused memory foam, plush comfort foam, PCMflux high resilience foam, high-density support foam, zoned support foam and high-compression pocket coils with a reinforced edge. Tempur-Pedic describes TEMPUR-Material as a one-of-a-kind material with an advanced cellular structure engineered to adapt and respond while you sleep.

What do trial, warranty and delivery look like?

Sweetnight gives the CoolNest Hybrid a 100-night trial with a requirement to sleep on it at least 30 nights, a 10-year limited warranty covering manufacturing defects such as a sag of more than 1 inch, and free U.S. shipping. Tempur-Pedic gives a mattress bought directly a 90-night trial with a recommended minimum of 30 days, a 10-year limited warranty, and complimentary white glove delivery that includes setup and removal of your old bed, typically arriving 7 to 10 business days after the order.

Tempur-Pedic adds a $600 surcharge per order for remote locations and Alaska and Hawaii. Sweetnight states that mattresses, bedding and bed frames ship free in the United States.

Who should buy the Sweetnight CoolNest Hybrid and who should buy Tempur-Pedic?

Buy the Sweetnight CoolNest Hybrid if you want a hybrid with a cooling cover, a pillow top and three thickness options, backed by a 100-night trial and a 10-year limited warranty. The Queen price is $499.99, the mattress ships free in the United States in 1 to 2 business days, and the brand asks you to sleep on it at least 30 nights before deciding. Choose the 14 or 16 inch model if you want the zoned support foam layer, since Sweetnight lists that layer for those two thicknesses only.

Buy Tempur-Pedic if you want a material the brand says adapts to your weight, shape and temperature, delivered with complimentary white glove setup and old bed removal. Tempur-Pedic offers Soft, Medium, Medium Hybrid and Firm feels, a 90-night trial with a recommended 30-day minimum, and a 10-year limited warranty. The brand also lists 0 percent APR financing for 36 months on select purchases.

Buy neither if a lifetime warranty matters to you, because both brands here list a 10-year warranty. In that case the Saatva Classic carries a lifetime warranty and a 365-night home trial, with free white glove delivery and old mattress removal included.

What does the Saatva Classic offer as an alternative?

The Saatva Classic is an innerspring mattress with a 3 inch Euro pillow top, a dual-coil design of triple-tempered recycled carbon steel coils, and patented Lumbar Zone Technology. It comes in three comfort levels: Plush Soft at 3 out of 10 on Saatva’s own scale where 1 is softest and 10 firmest, Luxury Firm at 5 to 7 out of 10, and Firm at 8 out of 10. Plush Soft feels soft and cushiony and body hugging, Luxury Firm balances cushioning with uplifting support, and Firm gives a floating on top feel.

Saatva lists a Queen price of $2,229 as the list price on its product page. The mattress carries a 365-night home trial and a lifetime warranty, and free white glove delivery includes in-room setup and removal of your old mattress. Saatva offers the Classic in two heights, 11.5 inch and 14.5 inch, and its foams are CertiPUR-US certified.

Frequently asked questions

Which mattress ships faster?

The Sweetnight CoolNest Hybrid is listed as in stock and shipping in 1 to 2 business days with free U.S. shipping. Tempur-Pedic states that white glove delivery orders typically arrive 7 to 10 business days after the order is placed, and that service includes setup of the new bed and removal of the old one.

Do both mattresses come with a pillow top?

Sweetnight lists a DuoSense pillow top on the CoolNest Hybrid as part of its comfort layer. Tempur-Pedic does not describe a pillow top on its mattress page; it describes TEMPUR-Material responding through a viscous response that absorbs the force of your body and its pressure points.

Can I finance either purchase?

Tempur-Pedic lists 0 percent APR for 36 months with select purchases, with no annual fee. Sweetnight shows the CoolNest Hybrid at a monthly figure on its product page rather than a financing term, so a shopper comparing financing should read the terms shown at checkout for each brand.

Which mattress should stomach sleepers consider?

Tempur-Pedic publishes a Firm feel among its four options, which is the firmer end of what the brand offers.
