Act fast! Our favorite luxury mattresses and their affordable alternatives in the last-minute Cyber Monday sales

The best luxury mattress we've tested, the Saatva Classic is, in our opinion, worth the investment. Follow our links to save $400 on the Classic and reduce a queen to the cheapest its been in months: $1,739 for a queen (was $2,139.) The Classic is a true all-rounder, deliver a breathable feel, incredible edge support and good motion isolation (for a hybrid.) It also has the best blend of cushioning and support of any mattress we've slept on, earning top marks for pressure relief. And you get a 365-night trial, lifetime warranty and free White Glove Delivery with purchase.

The DreamCloud packs a luxury punch for its price and at $699 for a queen it's incredible value for money. It's the best mattress in a box you can buy and we rated it highly for pressure relief, thanks to layers of therapeutic memory foam and individually wrapped coils. Best for side and back sleepers (we found it slightly too soft for stomach sleeping), the DreamCloud has a breathable build and good edge support, although it lags behind the Saatva when in both these categories. Still, with up to $599 of free bedding when you buy, you'll struggle to find a better value buy.

The best mattress for side sleepers we've tested, in our Helix Midnight Luxe mattress review we described its plush cushioning as creating a "weightless" feeling for side sleepers (no numb arms here.) Use our exclusive code TOMS27 to save 27% on the Midnight Luxe, a big step-up from the usual 20% off Helix mattress sale, reducing a queen to $1,751. While the Luxe is luxurious enough — just check out that pillow-top — for something even more indulgent consider the Helix Midnight Elite mattress. With our code, it's $2,737 for a queen.

The medium feel and plush build of the EGOHOME Hybrid made it a top choice among the side sleepers in our EGOHOME 12" Hybrid Mattress review. While you won't get the same indulgent pillow-top layer as the Helix, nor the zoned support, you'll find the contouring enough to relieve pressure. We also found the EGOHOME delivers a lot of bang for your buck, with a breathable build, excellent motion abosroption and strong edges. Make sure to use code EXTEND20 at checkout to save an extra 20% and bring a queen to $352.

With multiple layers of dense, thick foams, the Tempur-Adapt claims to deliver "legendary pressure relief." Our Tempur-Pedic Tempur-Adapt Mattress review team felt it lived up to that promise, helping alleviate aches and pains for back sleepers in particular. The motion isolation is also incredible, but poor temperature control is a slight ding. Tempur-Pedic's Cyber Monday sale is set to end soon so shop now to get $200 off.

The Zinus Green Tea mattress delivers a similar cozy, cushioned feel to Tempur Material, offering marshmallow pressure relief for those on a tighter budget. We tested the 10-inch version for our Zinus Green Tea Memory Foam Mattress review and found it ideal for side sleepers with no break-in period and we suspect this taller version delivers more robust support, closer to the feel of the Tempur-Adapt. While it won't be as good at easing joint ache as the Tempur-Pedic original, if it's luxurious cushioning at a lower price you want, the Zinus is the best memory foam mattress you can buy.
