Should I buy a topper to go with my OkiOki mattress?
Most customers find that OkiOki mattresses fit their needs without the use of a topper to provide additional softness.

If you find that after breaking in the mattress over a couple of weeks it’s still a bit too firm for your sleeping preferences, adding a mattress topper can give you that extra support you've been looking for. This helps you keep your existing mattress while making it softer and more comfortable to lie on, leading to a more restful night’s sleep.

Will my current sheets fit over my bed if I use a topper pad?
Most deep-pocket sheets can accommodate a mattress that's up to 22 inches in height, while normal ones can stop as short as 11 inches. Carefully stretch the fitted sheet on top of the mattress topper. Once all four corners of your bed are secure, tuck the fitted sheets into the side of your mattress.

To keep in mind, this mattress topper adds an additional 2 inches to the top of the mattress.

OkiOki Mattresses come as follows:

- The OkiSoft and OkiFirm Mattresses are 10 inches tall
- The OkiEasy and OkiFlex Mattresses are 11 inches tall

For those who want to try the topper pad first before they invest in new sheets, we suggest placing an extra sheet just around the mattress topper and then placing it on top of your mattress as it is. That way you can at least try it out without having this additional expense.

How long does it last?
Because this foam is so dense, it lasts for years. That is why all our mattress topper comes with a 3-year manufacturer's warranty.

Will the OkiOki Mattress Topper make my mattress sleep hotter?
The OkiOki Mattress Topper is designed to sleep cool and is made out of the same material as the cushion layer found in our OkiSoft and OkiOki Hybrid Mattresses. The mattress topper is filled with breathable polyurethane foam and is covered with a 100% polyester knitted fabric, ensuring that your new mattress topper will keep you cool and comfortable all night long.

How do I Care for my OkiOki Mattress Topper?
The OkiOki Mattress Topper comes with a removable cover, allowing for ease of washing.

Once the cover is removed, we recommend you machine wash on warm and tumble dry low. It will be tempting to wash and dry on hot — resist this urge! Heat drying could cause delamination and shrinkage. We want your mattress topper cover to last as long as possible. We do not recommend dry-cleaning the mattress topper cover.

Cleaning the inner foam is easy:

Step 1: Unzip the mattress topper cover and remove the inner foam.

Step 2: Fill a spray bottle with one part Mild Laundry Detergent and two parts warm water. Shake the spray bottle to mix the solution.

Step 3: Spray the entire surface of the urethane foam. Flip it over and repeat on the other side. Once you've finished spraying both sides, let the detergent solution set for 20 to 30 minutes.

Step 4: Wipe the detergent solution off with a damp washcloth. Do not spray with water.

Step 5: Allow the material to air dry, but avoid direct sunlight. Depending on how wet your urethane foam is, it may take 24 hours to several days to completely dry.
