    • Good quality wool, but some design defects.

      It's soft and healthy. No smell. I bought this for my daughter. She said over time the center got compressed so the bed became not flat and not comfortable. I also bought the King size, I turn it around every couple of weeks. It's hard to do since the pad is pretty big, otherwise you have the same problem. Even though, the edge still is thicker than the center, no matter what you do. It's hard to make it fluffy again.

    • Natural Sustainable Organic Topper for mattress~

      I built myself a layered mattress and find it provides the most effective sleep quality. I placed this topper over my mattress and find the organic natural scent of the wool to be inviting. I would like to buy a cover for this topper, but none is available. I highly recommend this topper~made in USA!

    • Perfection!

      I cant begin to say how happy I am with my purchase of this mattress topper! It truly does regulate your body temp, no cold spots, and its like sleeping on a cloud! No more sore hips and back! I cant recommend it enough. It is very thick and it stays put. We have two Twin XL and have pushed them together to make a California King I bought 2 of the twin XL and they are true to size. They are too thick to put in my dryer to fluff. Would have to take them to a Laundry facility with the big dryers. Know that this is REAL Sheep Wool and it does smell a bit like sheep, but not in a bad way. Once I covered them you could not detect it and it may disapate with time. You will be more than satisfied with this purchase!

    • Not as hot as I thought- comfy!

      I had a topper that was hypoallergenic and broke down, but I could not find a similar replacement- guess they all broke down. Anyway, I hesitantly got this wondering if it would be super hot- it is not and it is very very comfy!

    • Excellent organic topper surpassed expectations

      I've long considered adding wool to our beds for temperature control and comfort. When my 3 year old started complaining that her Naturepedic mattress wasn't comfy and she was constantly waking up sweaty, I finally decided to pull the trigger. I only wanted organic wool in organic cotton since the chemicals that create "washable wool" defeat the point of putting wool on your bed and, since wool is naturally antimicrobial and antibacterial, I'm not concerned with washing something you just "air to clean". Anyhow, I searched through a lot of the boutique natural living stores around San Francisco and even started looking in to buying from a local fiber co-op. However, when I found this Bio Sleep topper on Overstock, I jumped at the opportunity. The topper came quickly (it drop ships from OR) and it is soft and lovely. The wool inside is high loft and perfect for snuggling down into. There is also no sheepy smell. My 3 year old immediately knew there was something different about her bed when she climbed in (I didn't tell her it was on), telling me "My bed feels high and soft, Mommy. I think it's a snuggle cloud!" I now can't wait to add one to our bed along with the all-season comforter. Check the price pricing for each product on here, some sizes are cheaper direct, but the twin and CA king prices can't be beat!

    • Nice for Mild Hot Flashes

      Normally, I search for cool spots in bed during a hot flash. The natural wool fiber is much better than synthetics for dispersing/retaining body temperature. Once my feet are pre-heated, I sleep like a baby. When a hot flash occurs, I merely uncover slightly or roll to one side to cool off. I am very happy with this purchase!

    • So Comfortable!

      This pad costs a little more, but it is well worth it. Since I put this on my bed my sleep has improved dramatically. The organic wool ikeeps my body temperature regulated and doesn't bother my alergies. It is made of high quality materials, the cover is smooth, the wool isn't inclined to bunch, and the pad stays put on the bed no matter how much moving around I do. This is a luxury item that enhances restful slumber. What more could you ask? I highly reccomend this product..

    • We tried everything else, so why not wool?

      We have been seeking the Holy Grail of good sleep for years, experimenting with nearly every mattress and topper on the market (coils, latex, adjustable air, memory foam, egg crate, gel, sheep skin, etc.) The only thing we hadn't tried yet was the stuffed wool. So we figured why not? Not wanting to commit to a king size, we went for one twin, figuring we'd each try it out and if we liked it, we'd order another. Turns out it was a great idea. We now have two twin toppers that fully cover our standard size king bed, with the added bonus of easily turning and fluffing each time we change the sheets. (Can't imagine doing that with a single king size topper, since these things are anything but light.) Our base mattress is 100% latex, which means it's firm but not forgiving. Since we prefer firm, and not the sensation of sinking into a hammock (the feeling we get from other toppers), the wool is a great compromise. It provides cushioning for pressure points but doesn't make you feel like you're being swallowed. It does make the nights warmer, not a plus for me, since I'm a hot sleeper already, but a definite plus for my husband, who is often cold. But other than the heat issue (fairly easily solved by kicking off the blankets) I'd recommend these to anyone searching for pressure point relief without too much softness.

    Questions & Answers

    Get your product questions answered right here.
    • Why did you choose this product?

      • Matters too firm

      • Organic materials, looks like less bunching. Concerned about heat though

      • My daughter is going away to college and they will not allow mattresses other than supplied by the University. The beds are not comfortable and are flame retardant so I want an organic barrier between her and the mattress supplied for health and comfort.

      • I purchased this product in Full sized direct from the manufacturer Bio Sleep Concept in Full Size and absolutely find it to pair well over my 3 inch featherbed topper over memory foam to create perfect sleep! I sleep through the entire night without waking! I also find the natural scent somewhat comforting, like sleeping near freshly cleaned sheep. That may sound strange, but I could not find another way to describe this unfamiliar scent. The coupon offered by Overstock made this a worthy buy for my twin sized sofa bed used in my living room! Now to find a washable organic DUVET to fit over ensemble because I have not found 21-22" deep twin and full sized sheets to contain the mattress I have built!

      • I have some issues with memory foam heating me up at night. I remember a while back I had a wool topper and I slept cooler and more soundly so it was time to invest in another one for my new memory foam bed. That or buy a new mattress but I'll try this first.

    • How much loft, or cushioning effect does this product offer to a 200 lb adult. We have a high-end Tempurpedic mattress that we bought about 9 months ago and it is just too firm, causing back and or hip pain. Will this pad offer the cushioning that we need to soften up the too firm memory foam mattress?

      • Hello imagoodshot, we can appreciate the fact you want a firsthand account of the product. You will receive an email notification every time you get a response. Thank you for shopping with us.

    • What are the weights of the toppers in king and twin xl sizes? Thanks

      • Hello chrichri, the shipping weight for the twin xl sizes is 12 pounds. Please feel free to contact us again with any further questions. Thank you for shopping with us!

    • Is this treated with flame retardants?

      • Thank you for contacting us jnpn. This is naturally hypoallergenic, breathable and flame retardant. Naturally resistant to mold and mildew. Please let us know if you have any further questions.

      • No. It's all natural. That's why I love it.

      • Thanks Mary, for answering the question. Why didn't Overstock? Their answer seemed evasive.

    • I purchased this over the summer, and it is still sealed in its original packaging with shipping label. I would like to return it, even though it has been 3 months now. What steps can I take?

    • What brand is this mattress topper??

      • The brand name is Bio Sleep Concept.

      • That is not what I was told when I called. I was told it was by Vivetique. I don't understand what is going on.

      • I have purchased the wool topper and pillows in this product line and it is "Bio Sleep Concept." The products are fabulous, especially for us MCS sufferers.
