These Memorial Day mattress topper deals will make back sleeping more comfortable When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. (Image credit: Helix Sleep) If your mattress is a little too soft to be supportive for back sleeping, today's Memorial Day mattress sales is a great time to invest in a mattress topper for spinal support. One standout saving is 27% off the Helix ErgoAlign mattress topper at Helix Sleep with the code TOMS27. That brings a queen down to $364 from $499, which is an excellent price on a topper that promotes healthy spinal alignment and laced with cooling tech. Even the best mattresses can lack in support if it's approaching the end of its lifespan, but adding an extra layer of support can help promote a healthy sleep position. I've picked out three mattress topper deals for helping to not only firm up your mattress, but also offer enough support to making back sleeping more comfortable. Today's Memorial Day mattress and bedding sales means there are plenty of options to choose from, but these three are top of my list. Let's look at them more closely... 3 mattress topper deals to make soft beds more supportive 1. Helix ErgoAlign Mattress Topper: from $373.73 $272.54 with code TOMS27 at Helix Like the best mattresses for back pain, Helix's ErgoAlign mattress topper is specifically designed to help ease back pain. The topper is divided into three sections, with softer foam at the head and foot to contour to your body. In the middle, you'll find a denser foam that provides pressure relief and lumbar support to keep your spine elevated. There's also a GlacioTex cooling cover to keep sleepers cool (you'll often find this in the best cooling mattresses.) Use the code TOMS27 for 27% off the topper, which brings a queen size down to $364.03 (MSRP $498.66). There's also a 100-night trial and free shipping. 2. Serta ThermaGel Cooling Mattress Topper: from $49 $46 at Amazon If you're on a tighter budget, the Serta ThermaGel cooling mattress topper is a great deak, with a queen coming in at $59 from $74. Choose from 2" or 3" options for a topper that provides a decent amount of support and pressure relief. The breathable material also does a great job of preventing heat from building up, helping to dissipate it away from the body. Bear in mind that if you want the thicker topper, you'll be looking at $91.76 (was $116.80.) 3. Puffy Deluxe Mattress Topper: from $238 $202 at Puffy We rate the Puffy Deluxe as one of the best mattress toppers on the market right now. It comes in two versions, firm and soft. For those looking to firm up their mattresses, we'd unsurprisingly recommend the firm version. We tested this in our Puffy Deluxe mattress topper review, finding that while the dense firm did contour to pressure points, the topper still provided plenty of support and structure to the mattress where needed. A queen size will cost you to $245 (MSRP $288) and you'll get a very generous 101-night trial, lifetime warranty and free shipping.

See more Mattress Deals Jo Plumridge Social Links Navigation Mattress tester and sleep writer Jo Plumridge is an experienced mattress reviewer with several years' experience covering all things mattresses and sleep, and who tests memory foam, hybrid and organic mattresses. What Jo doesn't know about a boxed mattress isn't worth knowing, so naturally we tasked her with producing a series of features for Tom's Guide looking at all aspects of mattresses, from how to pick between latex and memory foam (it's a tricky one), to the seven mistakes people make when buying a mattress for the first time. When testing the DreamCloud Luxury Hybrid for Tom's Guide, Jo said: "I loved the back support and pressure relief it offered. Plus, it looks far more expensive than it is." When she isn’t writing about sleep, Jo also writes extensively on interior design, home products and photography.
