Custom Mattress Shape : Round Bed MattressAre you looking for a custom mattress for your custom bed? Did buy a bed set at a garage sale, estate sale, or an auction only to realize it requires a European size mattress or an odd international mattress size common in the UK, Ireland, Australia, etc?  We've heard it all!  :-)

Do you need a custom mattress topper, sheets, or mattress protector? MattressInsider.com has specialized in offering custom size mattress replacements for over 9 years. We can supply almost any odd size or unique shape that you can dream up.


We've made custom size mattress replacements for:


Need a mattress made with a hinge, cut corner, radius corner (click here for Airstream mattress replacements), or a beveled edge?


Contact us for a quote! We can customize the arrangement of layers and densities to fit your exact needs.


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.


Heart Shaped Mattress


Do you own one of those love-themed heart shaped bed hotels in Vegas? Or did you buy a heart shaped bed when you and your spouse were newly weds and now, 10 years later, you're struggling to find a replacement mattress? This is a shape which is challenging for most custom mattress makers because of all the tricky curves and edges. However, if you provide us with a template, we can make a custom foam mattress that fits perfectly. We can even make heart shaped sheets or heart shaped mattress protectors.  If you're a hopeless romantic who wants one of these mattresses, but you don't have the bed, more then likely, you could have a local fabricator make you heart shaped furniture or a heart shaped bed frame.  Try typing in "custom furniture near me" into Google.


Square Mattress


Say what? Yes, people actually buy square mattresses for play pens. They're also a few giant custom size foam mattress options which are in the shape of a square. Like Alaskan King Bed, Alberta King Bed, and Wyoming King Bed.


Can you make custom Tempurpedic mattresses?


If you're wanting to customize a Tempurpedic mattress to fit in a RV, boat, truck, etc, we have the ability to do this. You'd order the mattress from Tempurpedic and have it shipped to our factory. We can put radius corners, cut corners, beveled edges, hinges, and more. Depending on what's involved, we may need to sew a new cover from different fabric, but the tempur material, which is really what you're paying for, would still be in the mattress. Note: Customizing your Tempurpedic bed will void the warranty and the return policy. So we recommend trying one out in a store before you order one. I also need to mention that we're not affiliated in any way with Tempurpedic. If you're looking for a custom made Tempurpedic, give us a call for a quote.


I'm looking for a custom Purple mattress. Can you help?




If you ship us the mattress, we can cut it to the size and shape you need. We can also custom size Casper, Tuft and Needle, Leesa, Zinus, Puffy, Helix, Bear, Amerisleep, Nectar, Lull, Ghostbed, and most other bed-in-a-box brands. Note: We don't have any affiliation at all with any of those brands and having the foam cut to size will void the warranty and return policy. We can even sew replacement covers and zippered covers for those mattresses if you need them.


Can you make a van mattress for my Sprinter?


If you'e going to live and sleep in your van, you might as well be comfortable. If you're planning to do a van conversion, or you have a van hammock or van air mattress that's killing your back, order an odd size mattress from Mattress Insider. We can help you make a folding van bed, stowaway sofa bed, twin beds or any other type of van bed frame you're dreaming up.


If you're wondering, "will a king size mattress fit in a cargo van?" or "will a queen mattress fit in a cargo van?" The answer is, it totally depends on the van. You'll need to measure.


Are you the DIY type? We can also just sell you polyurethane foam or memory foam and you can make your own DYI van bed or mattress topper. There are plenty of tutorials on YouTube which show you how to do that.


Whatever your need is, we'll help your van interior ideas come to life! Then you can take one of those pictures from your new caravan mattress overlooking the ocean like the peeps on u/vandweller on Reddit. #vanlife


Here are just a few of the models we can make mattresses for: Ford Transit, Ram Promaster, Mercedes-Benz Sprinter, Chevy Express/GMC Savana, Nissan NV, VW bus, Vauxhall movano, VW Crafter, school bus, Renault Trafic, Knaus Boxdrive CUV, Citroen Wild Camp, VW California, Sportsmobile Classic 4x4.


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! 888-488-1468!
