Side sleepers, it's your last chance to soften your mattress for less with these 5 final Cyber Monday bed topper deals

This topper was voted the best for side sleepers, according to our Casper Comfy Mattress Topper review, thanks to its marshmallow-soft feel. The Casper Comfy Mattress Topper is usually at its starting MSRP of $199 over at Casper, so this Amazon deal that takes a twin down to just $125.20 really is one that can't be missed. The queen saving is even better, as you can get a 40% discount that reduces a queen to $179 (was $299).

Our Helix GlacioTex Premium Mattress Topper review praised this topper for adding cooling comfort to hard beds thanks to its 3.75-inch thick design and heat-dissipating GlacioTex cover. The topper is usually 20% off, but that's increased to 25% in the Cyber Monday sale, and you can use our special code TOMS27 to get an extra 2% off and reduce a queen to $364.02 (was $498.66). Benefits include a 120-night sleep trial and one-year warranty.

If you hate the 'hug' of memory foam, then side sleepers can turn to latex foam instead. Adding the comfort and support of memory foam minus the sink-in feel, the Birch Plush Organic Mattress Topper is great for side sleepers who also sleep on their back or front. Our Birch Plush Organic Mattress Topper review praised the premium, organic materials and we think it's great to put atop memory foam beds. Our code TOMS27 brings the usually 20% off topper down to $388.36 (was $532) for a queen, and extras include a 100-night sleep trial and an impressively long 10-year warranty.

The Tempur-Pedic Tempur-Adapt + Cooling Mattress Topper was our mattress topper winner in the Tom's Guide Sleep Awards, as it provides plush comfort to soothe side sleepers' shoulders, hips, and knees. A 30% Cyber Monday deal brings queen to $311.40 (down from $429), a fantastic price considering our Tempur-Pedic Tempur-Adapt + Cooling Mattress Topper review says it delivers the luxury feel of a Tempur-Pedic mattress for less.

The Naturepedic topper may be the most expensive topper on the list but its cloud-like softness and sustainable materials mean testers during our Naturepedic Adagio Organic Latex Mattress Topper review loved it. A 20% off deal for Cyber Monday (which as of writing, is still there) takes a queen (usually $599) down to $479.20. Plus, you get 100 nights to decide if you like it or want to return it (and returns are free if you opt for the latter) and a 10-year warranty.
