Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Mattresses can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new bedding should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Terrible Quality. Bunches up.

Dan 7/28/2024

These sheets claim to: 1. Stay tight with Staytight Corner Straps (Fitted-sheet corner straps) that create a secure non-slip fit. FALSE, they bunch up in the center all the time. They don't hold tight. Sheets that are half the cost of these work better. 2. They claim to be Moisture-Wicking (Keeps you cool). FALSE, I wake up alot with a damp feeling under me. Despite having the cooling Breeze Mattress Protector as well. I don't know how Tempur-Pedic's other sheets hold up. But from my experience with the Pro Air versions...I would recommend to use the classic cotton sheets. I don't think the claims with the other types hold up. 100% cotton.

Very comfortable and affordable sheet set

A Seattle Sleeper 7/27/2024

We chose this product after purchasing our new tempurpedic cooling mattress. The sheets are supposed to complement the product. They are comfortable, but seem very thin to me, which is perhaps the point? We have a king sized mattress, and the sheets also see a little large. While they don't pull off the corners, and that design element is very nice, they just seem oversized. Overall, we are happy with our purchase and may try a different variety when the cooler months roll around.

Quality

Tempur-pedic fan 7/26/2024

I have ordered sheet sets from Tempur-pedic in the past and loved them, but I do not feel that the pro-air sheet set lived up to the Tempur-pedic quality/name. They were thinner and did not fit the mattress as snug expected. The price was not cheap. I did, however, appreciate the bands on the corners that keep the fitted sheet on the mattress from coming off. That is was a plus that non-Tempur-pedic brand sheets don't usually have.

Cool but very thin

Hot sleeper 7/26/2024

We ordered these sheets to fit our new Tempur-Pedic cooling mattress. The sheets are very light weight and the fabric is soft. However, the sheets have a texture-obvious weave-and a thickness that takes time to get used to. They are great for summer and for a memory foam mattress like a Tempur-Pedic. Glad we got them on a sale.

Do not love them

Oswe 7/25/2024

I thought they were going to be softer and cooler. Once you sleep on them, the matress cover does not stay tight, the fabric stretches too much. I hope they get softer with a couple of more laundries. I should have purchased the classic cotton which work perfect.

Worst customer service

Very unhappy customer 7/25/2024

They need to change their return policy. The sheets were nothing like they were described. The size was wrong the material is very poor. I spent over $300 on sheets I can't use. I have one box not even opened, still won't take it back, but they will take used mattress back.

Hot sweaty sheet 7/24/2024

The sheets do not fit snuggly on the bed. It wrinkles and is not comfortable. The color was not all what I expected. I ordered a gray color and I received a blue color. I call the company immediately and was told I could not return the item. The sheets do not seem to keep the bed cool. I wake up in sweet every single night. I would not recommend these sheets

Best bed ever

They stay in place

Sailjewels 7/18/2024

We struggled with fitted sheets slipping off all night until we bought these. Couldn't find any other split king sets with corner straps. These cooler sheets aren't as soft and silky but they do seem to be cooler. Husband has always sweated heavily but the combination of fan cooled bed and these sheets has really solved the problem.

Jessica A 7/18/2024

The sheets are as advertised - very cooling, and a perfect compliment to the breeze bed. Only reason I didn't give five stars is because the fabric itself is a little rough, but it might soften from washing.

Not the Tempur-Pedic sheets from the past.

Disappointed. 7/18/2024

The corner elastic is a large downgrade from previous sheets we have bought from tempurpedic. The quality of the stitching has also decreased. I have a feeling these sheets wont last a year before they end up in the trash. The only reason I am keeping them is that they were on sale for half off.

Banana 7/18/2024

With tencel fabric, I was expecting a much softer. silkier feel but compared to our purple sheets, which are comparable in price, they do not measure up at all. However, compared to microfiber sheets, they are far superior.

Quality and Feel is awful compared to the Temp Cotton Sheets

Unhappy Customer 7/16/2024

We were super disappointed in the quality and feel of these sheets. We love our tempurpedic bed and Tempurpedic Classic Cotton sheets. So when we saw the bedding on sale and that these more expensive sheets were on a huge discount we thought we would try them out because we loved our Tempurpedic Cotton Sheets so much. However when we opened the package the feel is so cheap, scratchy and uncomfortable to lay on. No tot mention they feel so thin they will rip in no time. Upon contacting customer service we were told there was noting they could do. I DO NOT recommend wasting your money on these sheets at all. Super disappointed in how they marketed them, making them seem like the best quality sheets you could get at the highest discount (50% off) when really they just want to take your money so that they can discontinue them in a few months when people realize how bad quality they are. Yet not let you return them or exchange them. I would be happy to exchange them for the cotton sheets at the same price even.
