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.

Sheets are thin

Tdogg 12/9/2023

The sheets are much thinner than I expected them to be, which makes for a cool night of sleeping, but they still bunch up on top of the bed. The straps do hold the sheet onto the mattress, but it does not keep the sheets taunt as I was expecting.

Comfortable and cool sheets

Cozy and Comfortable 12/8/2023

These sheets are cool enough to let warm air escape but are also warm enough to keep you comfortable in bed. Very airy and light but also great quality!

Sheet set Corner ripped after 6 months.

Susan R 12/5/2023

I ordered these in May 2023. I purchased them for my Tempur-Adapt mattress. I have pictures that I guess I cannot attach. Nice sheets but for the price they should last longer than 6 months.

Terrible Quality

Disappointed Buyer 12/4/2023

I bought these sheets for my brand new tempur bed as well as the tempur mattress protector. These sheets feel terrible, they are perforated and feel rough. Two of four corners tore within four days, called customer service and they will not return their defective product.

The Best Sheets

Thomas 12/3/2023

Honestly, I think these are the best sheets I have ever owned or even slept on. I've always been kind of cheap when I've bought sheets in the past, but I think those days are behind me. The corner straps are nice too.

Horrible sheets....clammy...don't breath

JC 12/1/2023

Only used them one night. Sheets are given poor name. Not Pro Air at all. Didn't allow free flow of air...so sweated most of night with these. Since no return to you, I returned them to the dumpster. Not satisfied in the least.

Good sheets for hot sleepers

Sleeping Beauty 11/28/2023

I didn't like them at first because they felt rougher than I'm used to, but after a few washings they softened and are comfortable. They are great for a cooler sleep and thus are as advertised. I gave them 5 stars because they do what they advertised and are comfortable after several wash cycles.

Esm297 11/27/2023

rough and thin material

Ugh! 11/27/2023

I have never slept on such bad sheets. These make me think of prison garb. It had stated 1000 thread count, I believe, but how can that be true? When you look at them they have like a boxed weave "airy" look to them. CHEAPLY made. YUK! I bought 2 sets, which is allot of money (even though they were on sale)! I really feel cheated......:( This is coming from someone who owns a tempurpedic Bed and about 6 "old" sets of the most soft satiny tempurpedic sheets

ticked off 11/26/2023

terrible quality and even worse customer service. Never buying another tempurpedic product again. It's a shame, because I love the mattress. Wish I could return it now after this experience. Never again.

Disappointed

Disappointed_314 11/26/2023

I purchased two of these sheet sets online. I did not like the texture. It reminded me of rice paper and felt thin. Also, the sheets do not stay on my bed when I move the base up and down. I wish I could return them for a refund but they do not offer returns. I am really disappointed with the contrast in quality between the mattresses I purchased and these sheets.

Great Quality, fit's beautifully, washes well, comfortable

Flower Mound Mom 11/22/2023

The sheets are very soft and comfortable. They fit well and wash beautifully. They came out of the dryer without a wrinkle. My dog Charlie loves them also and he is very fussy about the sheets he sleeps on. I would not hesitate to recommend them!

Great sheets

Jnealer 11/21/2023

These sheets fit our RV King perfectly. I like the way the corners are done - they don't come off. Also, the sheets have very little stretch - I don't like wrinkles in my sheets. Very light weight - great for summer.

Got them as part of the promotion, they look a little meshy new but have washed up soft and definitely pair well with the "cool" mattress.
