The 9 best mattresses and toppers without fiberglass to buy in Cyber Week sales

1. Saatva Classic: from $1,095 $695 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 treament 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. There are monthly Saatva mattress sales and deals to save you around $200 to $250 on the Classic, but we have an exclusive $400 saving on every size until the 30 November. That reduces a queen to $1,595 (was $1,995), which is superb for a luxury fiberglass free mattress that comes on a year's trial, with a lifetime warranty and free old bed and foundation removal.

2. Helix Midnight: from $702.20 $936.30 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 25% off sale left over from Black Friday is currently still in place for Cyber week, so you can save over $400 on a queen Midnight with code CYBER25. Plus, your order will come with a free bedding bundle worth up to $418, as well as free shipping, a 10-year warranty and 100-night trial. As mentioned, all mattresses from Helix are fiberglass-free, so if you’d like something more luxurious, the Helix Midnight Luxe is also 25% off. Alternatively, if you’d like to experience the Helix Midnight for less, check out our Helix Plush Mattress Topper deal further down. 

3. Birch Natural Mattress: from $1,496 $1,124 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, but Birch is now knocking 25% off for Cyber Monday with the code CYBER25. With this code, you can take a queen size down to $1,592.80. Tied-in with the price is a 100-night sleep trial, free shipping and a 25-year warranty.

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 save up to $591 with the extended Cyber 35% off sale.
