If you're shopping for a mattress without fiberglass, you're in luck as there are some big savings to be had on the year's best fiberglass-free beds and mattress toppers. Brands including Bear Mattress, Birch Living, Saatva, Helix and Turmerry are still running sales on fiberglass-free mattresses and toppers, and we've rounded up the best deals right here.

The best saving is a deal where you can now save 30% on the Bear Original Mattress at Bear Mattress,but there are plenty of other fiberglass-free mattresses on the market. One such mattress is the Saatva Classic, which is currently No 1 in this year's best mattress guide.

Fiberglass is a synthetic composite material made from glass and recycled plastic. It's used in some mattress covers and some memory foam mattresses as a cost-effective fire retardant. It poses little risk to your health when fully, properly sealed, but direct contact can cause breathing problems and irritation, among other health issues. This could happens if a mattress cover is opened by mistake (against the manufacturer's advice), or if it's damaged or ripped.

If you'd rather not take the chance, there are some good deals on the best mattresses without fiberglass, plus toppers if you have a much smaller budget. Here's what we recommend...

The best mattresses without fiberglass to buy now

1. Saatva Classic: from $1,399 at Saatva

The best mattress without fiberglass overall

This is our top recommendation for the the best mattress without fiberglass, chosen because of its high levels of pressure relief, lower back support and head to toe comfort. The Saatva Classic is like having a luxury hotel bed in your home, and because it's made without fiberglass or any other harmful or toxic materials you can sleep easy at night. As we explain in our Saatva Classic mattress review, this luxury innerspring hybrid is handcrafted in the US and made from recycled steel coils, CertiPUR-US certified toxin-free foam, plus an organic cotton cover treated with a botanical treatment to banish mold, mildew and bacteria. For those of you seeking a mattress without fiberglass, the important thing to note is that the Saatva Classic uses a natural flame retardant made from thistle pulp. Currently, a queen is $2,099, but keep your eyes peeled for monthly Saatva mattress sales and deals for cheaper prices. It also comes with a generous year's trial, a lifetime warranty, and free white glove delivery.

2. Helix Midnight: was from $936.30 $702.20 at Helix Sleep

The best mattress without fiberglass for side sleepers

All Helix mattresses are made without fiberglass and instead use yarn made from chemical-free Rayon fiber as a flame retardant. The Helix Midnight is ranked as our best mattress for side sleepers thanks to its foam providing a comfort that our Helix Midnight mattress review describes as ‘dreamy’. In addition to foam, this hybrid uses a coil system which promotes better airflow, keeping hot sleepers cool. However, as with most mattresses designed to support side sleepers, the Helix Midnight is be too plush for stomach and back sleepers and those with heavier bodies. Regular Helix mattress sales mean you’ll never have to pay full price for the Helix Midnight, either. A 20% off sale currently takes a queen Midnight to $1,099 (was $1,373.75). Plus, your order will come with free shipping, a 10-year warranty and 100-night trial.

3. Birch Natural Mattress:was from $1,373 $1,099 at Birch Living

The best mattress without fiberglass for back sleepers

As one of this year's best organic mattresses, the Birch Natural Mattress is made without fiberglass and instead uses organic wool as a flame retardant. Thanks to the cooling properties of Talalay latex and moisture-wicking breathability of organic wool, our Birch Natural mattress review found that the bed is one of the best organic mattresses for hot sleepers and was responsive and firm enough for front and back sleepers. Our testers did note however that it may not be best for co-sleepers due to weak motion isolation, while side and lightweight sleepers may want something softer with more memory foam “hug”. The mattress is often on sale at 20% off,so you can regularly take a queen size down to $1,499 (was $1,873.75). Tied-in with the price is a 100-night sleep trial, free shipping and a 25-year warranty.

4. Bear Original Mattress:was from $699 $499 at Bear Mattress
The best mattress without fiberglass for couples

Opting to use the eco-friendly rayon as a flame barrier instead of fiberglass, all beds by Bear Mattress are 100% fiberglass free including their Bear Original mattress. The mattress’s all-foam construction, including gel-infused memory foam and high density support foam, creates a soft, contouring comfort that supports back, stomach, and side sleepers. In our Bear Original Mattress review, testers praised its excellent motion isolation, which (teamed with a popular medium-firm rating) makes the mattress ideal for couples. While reviewers did find it sleeps quite warm, the Original is Bear's most budget-friendly mattress and you can pick up a queen for $699 (original price: $998). Along with this huge saving, the bed also comes with a 120-night sleep trial, a lifetime warranty and free shipping and returns. Overall, this mattress deal is great value.

The best mattress toppers without fiberglass

1. Turmerry Latex Mattress Topper: was from $209 $109 at Turmerry
The best mattress topper without fiberglass overall

All Turmerry mattress toppers use a layer of organic certified wool as a flame retardant, including their Organic Latex Topper. So there's zero fiberglass here. The 100% natural, hypoallergenic topper comes in four firmness levels (soft, medium, firm, and extra firm) and three thickness levels. The topper is designed to provide zoned pressure relief in the shoulders, hips and back, delivering extra comfort when side sleeping.
