Custom Made Mattress Options:

While our most common request is for a custom size memory foam mattress, we also offer odd size latex mattresses, innerspring mattresses, gel foam mattresses and more.

We have a large assortment of the most innovative foams available including Bayer and Preserve Visco Elastic Memory Foam, Natural Latex from Latex International, Gel Memory Foam, and Plant Based High Density foams. All custom mattresses will be made with a luxurious cover in one of our 3 fabrics: Certified Organic Cotton, Cool-Max by Dupont, or Bamboo.

We use only the highest quality USA made open-cell plant based temperature neutral foams. All of our memory foam and high density foams have been tested by the independent laboratory Certipurus and have been certified to be non-toxic.

All custom mattresses come with a 10 Year Manufacturers Warranty. All of our mattresses pass the strict federal CFR 1633 flame retardant mattress standards.

Production time is anywhere from 5-7 business days (call for lead time). Transit time to the east coast is 2-3 business days and 4-5 business days on the west coast. Your custom made mattress will be compressed, sealed in plastic, boxed, and shipped to you via FedEX Ground.

A Few of Our Customer Testimonials:

“So glad I decided to do the custom size mattress. It fits perfectly in the little Roadtrek. It feels nice and firm yet comfortable. Thank you for a nice product and great customer service!” Katherine, Los Angeles CA.

“The custom mattress I ordered and received from you is excellent. I received it 2 days earlier than projected. I will certainly recommend Mattress Insider to anyone who needs a mattress.” Deanna Huston, Greenwich, CT.

“Thank you so much for taking my order and getting us two of the most comfortable mattresses I have ever laid upon! We took them to the RV dealership today and put them on the bunk beds. They fit perfectly!

We also gave Rick at Nortwood RV your website as he was really impressed with your mattresses as well. Thank you again for all your help and I will now be ordering the encasements and bedding for them. Thank you again, Jonathan and Mattress Insider!!”
Darlene Foster, Orlando, FL

How to Obtain a Quote for a Custom mattress Size  
  1. Using a tape measure, obtain the dimensions of the surface the mattress is going on (plywood, platform bed, plywood, etc). Measure the longest length and the widest width. If it’s an odd shaped mattress, we can still give you a quote over the phone, but we may need a template or a schematic before we start production from your RV or Boat manufacturer or we can tell you how to make one).
  2. If possible, obtain the existing mattress dimensions (not required but helpful).
  3. Note the height of your existing mattress (if it’s still available) and note if you have any height restrictions (mattress is close the ceiling, you have a low headboard, etc)
  4. Double check your measurements one more time. Because of the labor and cost of materials involved, all custom mattresses are non-refundable once production is started and there are no returns, cancellations, or modifications.
  5. Give us a call for a quote! 1-888-488-1468!

Please note: due to the nature of constructing custom mattresses, allow for up to a 1.5″ deviation in either direction from the original measurements. We cannot guarantee that custom builds will match your original measurements exactly (but we do our best, and generally isn’t an issue!). If you have any questions regarding this, please do not hesitate to give us a call!

Hello,

I mistakenly thought I could repurpose my old mattresses by putting two twins together to form a King, but learned that twins are not the same length as a King bed - after I purchased a non-refundable bed frame. Subsequently, there is a 6” gap at the foot of the bed. This poses two problems: 1. There’s a gap between the mattress and footboard. 2. A King fitted sheet (and mattress pad) does not fit properly on the two twin mattresses.

How much would it cost to make a 80”x6”x8” block to fill in the gap? Thanks!
Natalie J on Jan 13, 2018
BEST ANSWER: Hi Natalie! You may be better off getting a new mattress as adding a block would not be very comfortable for sleeping.

Can you make flex top mattress 76x84?
June H on May 27, 2018
BEST ANSWER: We purchased a custom King foam mattress from Mattress Insider. It came as quickly as they promised, they called me to verify that I had measured the area correctly and we love the mattress. We're in our mid to late 60's and in the past have been uncomfortable sleeping. Sore hips mainly. Our mattress has two or three layers (don't remember specifically) and is holding up well; it's very comfortable. I have recommended MI to others needing mattresses; custom sized for RVs or just for their home. Good mattress, excellent price.

I need 2 bunk bed mattresses but one of the corners is at a slant is the style in our camper. Do you make those?
Jaime H on May 25, 2020
BEST ANSWER: Yes, they do. We had one custom made for our Airstream. It is curved at the top and end. Airstream gave us the specs or measurements for the company to make a perfect-fit mattress. About two years after we bought it, a few threads on one side started to come out. It was just the cover. Mattress Insider sent us a brand new cover based on specs. Fit perfect. No charge. We will buy from them again. Oh, what we bought was a CoolMax 5 inch topper to make the camper bed more comfortable. Works perfect!

Your center for customized mattresses and everything that goes with them!
This site is a godsend for people who have an antique bed that doesn't take a standard mattress. We purchased the coil mattress and were delighted with how firm and comfortable it is. Also you can get a pillow topper and a waterproof, bedbug proof mattress protector made to fit your special size. There is nobody else out there that I could find who could all this!
