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.

Thin Sheets Scratch Against Your Skin

MQuizzel 5/25/2024

For the price we paid, I was expecting soft, luxurious sheets. These are extremely thin and the waffle design is scratchy against your skin. We've tried washing them several times and it doesn't help. I would compare it to hospital bedding. The only reason you stay cool is because the sheets are so thin. Not at all what I was expecting from Tempur-Pedic, especially at the price point we paid.

Don't waste your time or $$

Chicagodreamer 5/25/2024

These sheets are like the dentist bib. They are super thin and don't feel nice. I called to complain and see if we could exchange them and they won't do anything for me. I even asked if I could just get a discount on another set of sheets and they refused.

light and cool

sleepy 5/24/2024

These sheets were exactly what I was looking for. They are very light and help keep me cool through the night. They have a slight texture to them, but nice, quiet, and soft.

AMAZING SHEETS♥️

Comfortable in Carolina♥️ 5/24/2024

I just placed my order for another pair! I so love the feel and sleep experience they provide on my luxe breeze mattress! They are light, breathable and airy allowing the mattress to provide the support and feel it's designed to give with this no barrier coverage. Yet, the sheets are as luxurious as a high thread count Egyptian cotton sheet. Also, they truly stay put with this ingenious strap around the corners of the mattress. This design makes it easy to make the bed as well!

Quality not good and poor customer service

Unhappy customer 5/23/2024

When my sheets arrived, I washed them before putting them on my bed. I followed the exact cleaning instructions. The sheets came out like sandpaper, I could not sleep on them. I called customer service and let them know the problem, under no circumstance would they take them back after spending over $100. Their moto say's they 100% stand by their products, they absolutely do not. I have been in customer service for many years and this by far was the worst experience.

The best sheets out there!

Happy sheet owner 5/21/2024

I have tried so many different styles and different materials of sheets and always go back to Tempurpedic. They are the only sheets that will actually stay on. The corners do not come off and no loose fitting. I won't buy from anywhere else!

Hard Pass

Never again 5/20/2024

These sheets appear to be very low quality. I think they feel like a small step up from a cheap mattress pad protector. I was very disappointed and was shocked that this company refused to accept the return of the additional sheet set I ordered that was unopened!

Nice sheets, but not the best in this price range

Slater 5/20/2024

Got these sheets as part of a half off promo, and at that price I would say they were a solid buy. They stay cool and feel pretty soft to the touch, and hold up well in the wash. However, at their normal price point... my partner and I strongly prefer a few other brands which feel significantly softer and look amazing. These have a slight pattern that just looks... odd, to be frank. So, I would recommend waiting for a sale- and then give them a try

Exactly what you would expect

Tempur fan 5/17/2024

If you are looking for breathable and cooling sheets, to help you sleep comfortably throughout the Night, then these are the ones for you! I have always been a fan of tempurpedic products so these pair perfectly with my tempurpedic mattress and adjustable base. My partner and I both have been sleeping amazing since we got these.

Very soft and cool to touch. Well made and feels comfortable. Ensures that it serves as a cooling layer and doesn't take away from the mattress's coolness.

Everything is Excellent

Larry 5/16/2024

The linens, new LuxeBreeze bed, and the Ergo base are perfect. Replaced a 10 year old Tempur-Pedic (it was time 😉) and the cool, comfortable firm bed with the high-end cool linens and the Ergo base (raised it up to sit comfortably and write this) are phenomenal. Lower the base a bit when it's time to sleep and I'm out like a light

Seem to be helpful and good with the cooling mattress. Nice soft sheets but thinner than I expected. Only washed once so I'll see how they hold up...good sheets overall. 8/10 rating

Not a happy sleeper 5/12/2024

I have an adjustable base for my Tempur-Pedic, and every time I move it in the slightest these sheets are unable to move with the mattress and instead just pull off or put undue pressure on the elastic straps that are corner to corner. I have tried several sets of sheets to fit my Tempur-Pedic and by far and away. This is the worst. It's hard to believe that the worst sheets to fit my Tempur-Pedic would come from the actual company.
