We were skeptical at first. The price seemed low compared to what the bed mfg charges for their sheets and we didn't know if they would fit. WOW! Excellent construction, fit perfectly and are very comfortable. Ordered another set. Quit paying outrageous prices.

I love them. Perfect fit and feels nice on your skin while your sleeping.

These fit our split top king but are a little thin, the color was nice! Fit was exact! I would buy again especially for the price. Sleep number is so expensive and they do not last!No pilling at all, soft material but thin, there is absolutely no temperature control at all !

I love the deep rich blue color. The fabric is soft and had held up well in laundry washes. The color has stayed true during washes also. I recommend these sheets for a comfortable nights sleep.

We purchased a sleep number flex head bed and my sisters told me to look to Amazon for sheets. Found these and purchased. They fit great and stay in place. There is elastics on each corner to hold the fitted sheet in place. They wash nicely and have held up well so far!

It’s hard to find good sheets for a Sleep zNumber bed without breaking the bank, these sheets are good.They feel a little thin, but are holding up very well after multiple washings. No rips or tears so far.My Sleep Number branded sheets held up for a few years before tearing at the seams and actually wearing through where my heel hits, but I did not want to pay $300 for a set of sheets, that’s just crazy money when a regular set of good sheets is $50. Sleep Number takes advantage of their customers. If I was doing it again I would never buy a Sleep Numbrr bed.Again, very good sheets at a very good price. Buy them.

I was hoping this sheet set would be comparable to the sleep number sheets. And based on other reviews it seemed like it was a reasonable hope. They’re fine, but that’s it. The thickness of the sheets is pretty good so they will likely wear well. But they are not particularly soft and they wrinkle like crazy. I might buy from this company again because they do feel like decent quality. But I might look for a softer fabric in the future.

We have a top split king size sleep number bed. We bought 2 sets of sheets from Sleep Number, they were $300 each!! They ripped within a few months, one set ripped within 3 months and the other set had a strap that ripped after the 2nd time we put it on the bed. We made due and just kept using them because we didn't want to spend another 300.00 on sheets, bad quality sheets no less. It got to the point that we couldnt use those sheets anymore, the tears were getting bigger. Luckily my husband found these. We've washed them several times and they are still perfect. Other reviews talk about how big they are but ours fit perfectly, possibly because we also have the heating/cooling mats on our bed too. Now that we've been using this set and love them we can feel comfortable enough to buy more sets and never again buy sheets from Sleep number.

I bought these for our RV and they fit perfectly. I washed and dried them normally before using. No popping off the corners of our 10" mattress. I added a mattress topper to our mattress and they still fit perfectly. They have great elastic to hold it in place. The sheets were nice and soft - only downside is that they are quite thin. I'm still going to give them 5 stars because other than being thin I was really happy with them. Not sure how long they will hold up - but should be ok for a couple camping seasons!

Soft and comfortable sheet, nice colorThank you

Very good helped with reducing body heat whilst sleeping

this is my third set over the years. Fits well, I like the new way the fitted sheet is made, all areas rienforced and washes well

Nice color
