100% Organic Washable Wool Mattress Pad Topper | Twin Ex-Long

100% Organic Wool Mattress Pad — Twin Extra-Long | Washable, Reversible, Woolmark Certified

Quick answer: The Twin-XL version of our plush 1" organic wool mattress pad, sized 39" × 80" for extra-long twin mattresses — dorm beds, adjustable bases, and guest rooms. Reversible (wool side for year-round temperature regulation, 100% Japara cotton side for warmer months), machine washable, Woolmark certified, and hypoallergenic. Fitted elastic skirt fits mattresses up to 13" deep.

Wool naturally regulates temperature and wicks moisture — keeping you cool on hot nights and warm on cold ones — without synthetic chemicals or treatments. The Twin-XL size is 5" longer than a standard Twin, making it the right fit for dorm beds and adjustable bases that standard pads won't cover properly.

WHO THIS IS FOR:

  • Twin-XL mattresses — dorm beds, adjustable bases, guest rooms
  • Hot or sweaty sleepers wanting natural temperature regulation
  • Allergy sufferers — hypoallergenic, dust-mite and mildew resistant
  • Eco-conscious shoppers wanting renewable, biodegradable materials

FREQUENTLY ASKED QUESTIONS

Why Twin-XL instead of regular Twin?
Twin-XL is 5" longer (39" × 80" vs 39" × 75") to fit extra-long twin mattresses common in college dorms, adjustable bases, and some guest room setups. A standard Twin pad will leave the foot of the mattress uncovered on an XL bed.

Is it reversible?
Yes — plush wool on one side for year-round temperature regulation, breathable 100% Japara cotton on the other for warmer months. Simply flip it seasonally.

Does wool sleep hot?
No — this is one of the most common misconceptions. Wool is a natural thermoregulator: it wicks moisture and allows airflow, keeping you cool in summer and warm in winter. It outperforms synthetic fills for temperature regulation.

What is Woolmark certification?
Woolmark is the world's leading wool textile certification, guaranteeing 100% pure new wool meeting strict quality and performance standards. It's the gold standard for wool bedding authenticity.

Can I machine wash it?
Yes — gentle/wool cycle, mild detergent, no bleach or fabric softener, tumble dry low. A standard home washer handles the Twin-XL size easily.

Will it fit my adjustable base mattress?
Yes — the elastic skirt fits mattresses up to 13" deep and flexes with adjustable base movement. Confirm your mattress height is 13" or under before ordering.

Is wool hypoallergenic?
Yes. Wool naturally resists dust mites, mildew, and mold without chemical treatments — making it one of the best choices for allergy and asthma sufferers. It's also naturally fire resistant.

How does this compare to the standard Twin Organic Wool Pad?
Same product, same fill, same quality — just 5" longer. The standard Twin version is 39" × 75". Choose Twin-XL if your mattress is 80" long.

Brilliant!

I am very happy with my wool mattress toppers. I have adjustable beds with memory foam mattresses, so I bought two twin xl toppers.
My husband thought the bed was too soft, and would wake up with a sore back, because he would sink too deep in the mattress. The topper solved his problem brilliantly.
I was getting too warm with my memory foam mattress, despite heat dissipation “technology”. I can say that I sleep cooler with my new wool topper. So it’s a win on both fronts. I strongly recommend.

Hello Luminita - We appreciate your honest review. Everybody sleeps differently and is unique. There is nothing better then waking up with a nice cozy bedding in the morning. The twin extra long size is a specialty size that we carry. Please check out our wonderful Sleep Blog.
