I'd talk you out of the Benedict Wooden Bed Frame. Dreams sells it as a wooden bed, but its own listing describes the finish as "natural wood effect" and "walnut wood effect", and if you're paying for a wooden bed, I think you should get one. Choose it only if you like this exact rustic look and know you're buying the look, not solid wood.
Wood effect is a finish, not a material
A wood-effect finish is a printed or textured surface that imitates timber, usually over a board underneath. It can look convincing, and the Benedict's rustic grain texture is designed to. It won't age the way wood does, though: chips and scuffs show the material underneath, and you can't sand it back. Solid wood lasts. It's the reason I'd steer most people to a wooden frame in the first place.
In Dreams' photos the headboard and a low footboard are covered in vertical reeding, the ribbed look that's on every other headboard in the shops, in a dark walnut tone. It's handsome in pictures. Ribbed finishes take knocks along the ridges, though, and on a wood-effect surface a chipped ridge can't be sanded back.
The rest of the bed is sensible. It has solid wooden slats for a firm, flat base and a curved headboard. Dreams' assembly guide shows a metal centre bar with two middle feet under the base, so the middle of the bed is held up.1 There's matching bedroom furniture in the range. It weighs 44kg flat-packed.
Only for the walnut look on a budget
If you want the walnut look on a tight budget and you'll treat the bed gently, it does the job. Avoid the Benedict if children will climb on it or if you were hoping it would last as long as the furniture it matches. Ask Dreams what the frame is made of under the finish before you buy, because the listing doesn't say.
What to buy instead
The Penelope is solid wood in a walnut finish on solid slats, and it's the one I'd buy instead. If you'd like a little softness with your wood, the Brimsley is solid rubberwood with an upholstered headboard. Both are wooden beds in the sense you meant.
