Boyd Ultra 12″ 6-Zone Smart Zone Bed review: should you buy it?

The Boyd Ultra 12" 6-Zone Smart Zone Bed gives you two ways to choose firmness: a number or a foam feel. Choose Adjustable for a numeric setting from 1 to 100 in single-digit increments. For reversible comfort foam, peak side up is Plusher Feel, while flat side up is Firmer Feel. Pick the foam orientation whose named feel matches what you want. If you prefer deciding with numbers, use the adjustable option; if you prefer a feel label, use the foam's peak-up or flat-up setup.

The Night Air sleep system is tested to support 1,000 lbs.

No: Sleep Sage says the Boyd Ultra's lumbar adjustment is a comfort feature, not evidence that the bed treats back pain. Boyd says its dedicated lumbar zone supports the lower back through the night. That is the brand's support claim; it does not establish pain relief. Treat the zone as a comfort adjustment, not a reason to expect back-pain relief. Do not buy it as a back-pain treatment based on lumbar support alone.

Its cooling features are a fabric cover and a gel-and-latex foam. The cover is Cooling Ice Lux™ fabric, paired with 2.5" Cooling Convoluted Gellux® Engineered Latex Foam. That foam combines liquid gel with engineered latex for cool, responsive comfort. If cooling materials matter to you, use these listed components to compare mattress descriptions and decide which features belong on your shortlist.

At the Queen list price of $3,699, this bed may be worth the cost if adjustable firmness matters to you. Firmness is adjustable from 1 to 100 in precise single-digit increments, so you can fine-tune the feel rather than settle for one fixed setting.

Prices change, so check the live price before buying. If that control is not useful to you, the price may be hard to justify.

Ultra 12" 6-Zone Smart Zone Bed list prices by size

Height: 12 inches

This is an air-core adjustable bed with foam parts and heavy-duty TPU air cores. Its listed layers run from top to bottom:

• Cooling Ice Lux™ Fabric Cover: fabric.
• Cooling Convoluted Gellux® Engineered Latex Foam: liquid gel and engineered latex, 2.5 inches thick.
• High Density Foam Perimeter Support Tray: high-density foam, 9.5 inches thick.
• Also included: heavy-duty TPU air cores, separate from the foam parts.

The cover is Cooling Ice Lux™ fabric, and the listed CertiPUR-US certification covers flexible polyurethane foam only. Latex foam is outside its scope, so this is a check on that foam, not the whole bed. It does not speak to the fabric cover or other parts. If you are comparing materials, check which foam type the certification covers.

Night Air says the Boyd Ultra's fire barrier is natural cotton. The brand also says it has never used fiberglass as a fire barrier. To check the materials on your mattress, read its law tag. The tag lists the materials used, so check its wording for what is named as the barrier.

The brand lists a platform bed frame and an adjustable base as compatible with this bed. For an adjustable base, the processor must have a 110 volt outlet. Check for one before choosing that setup. The brand says an optional adjustable base is offered with this model.

The comfort foam's reversible design lets you choose a feel: peak side up is plusher, while flat side up is firmer. Pick the side that suits your comfort preference. Night Air says to try a setting for at least 5 nights before judging how your body adjusts. Stay with your chosen setting for that period, then decide if you want the other feel.

The brand says delivery takes 7-10 business days after it leaves the warehouse. Plan around that window rather than a set arrival date. If you are replacing a mattress or moving, keep your schedule flexible so the delivery timing does not dictate a fixed day.

Boyd says this bed’s trial lasts 100 nights, and a return costs $99. That fee adds to the cost of sending it back, so include it in your budget. The trial excludes power bases, foundations, platform bed frames, heavy-duty bed frames, pillows and accessories.

Boyd says its warranty covers defects, with a sag cutoff of 2 inches and exclusions for certain damage. A shallower dip does not meet that measure, so it does not qualify as a sag issue. Coverage does not apply to tears, punctures, or cuts caused by accidents, abuse, improper component installation, or consumer negligence. Compare the dip with the cutoff and consider how any damage occurred before deciding whether to pursue a claim.

Nightairbeds.com owners praise comfort and support. Its latest visible 2024 owner comments also praise easy adjustments. One comment calls the digital hand controls intuitive and says adjustments are effortless. If easy changes matter to you, those are the benefits owners highlight.

Nightairbeds.com lists 4.9 from 66 reviews on its own site; read that as site-hosted feedback, not an independent rating. Performance Sleep Systems lists 4.9 from 98 online ratings in a cross-web aggregate. Keep the figures as separate views rather than combining them into one owner score.

The practical comparisons are Boyd's own 11-inch, 14-inch, and 16-inch builds first, then rivals for adjustable firmness or a budget-first foam bed. Choose the 11-inch build for its 1.5-inch comfort-foam layer. The 14-inch build has 3.5 inches of reversible, 5-zone gel memory foam. Choose the 16-inch build for a copper-infused cover and 4.5 inches of reversible, 7-zone gel memory foam.

For couples who want remote-adjustable firmness on each side, consider the Saatva Solaire Adjustable Firmness Mattress. Its Queen price is $4,789; Sleep Foundation gives it an 8.7 overall test lab score and notes 50 remote-adjustable settings. For budget-first shoppers, Brooklyn Bedding CopperFlex Memory Foam has a Queen price of $865. Sleep Foundation ranks it first on its Best Cheap Mattresses list and gives it an 8.8 overall test lab score. Sleep Foundation lists its medium-firm foam profile as a fit for side sleepers over 130 lb, back sleepers under 130 or 130 to 230 lb, and stomach sleepers under 130 lb.
